Technical Corrigendum for ISO/IEC 10179: DSSSL

This document lists currently reported defects in ISO/IEC 10179:1996. It has been compiled by James Clark, the Defects Editor for the standard.

Defects in Clause 7: DSSSL Document Architecture

This must be aligned with AFDR in the HyTime TC.

7.1: An external-specification element can count as the first specification for the purposes of an external-specification element without a specid attribute.

Defects in Clause 8: Expression language

8.2.1: Delete the phrase ", or assignment of".
8.3.1.4: In the example, the expression (lambda x x) should be (lambda (#!rest x) x).
8.5.7.1: Clarify that redefinition of units works like normal redefinitions.
8.5.7.22: The description of inexact->exact is unhelpful given that any quantity with non-zero dimension is inexact.
8.5.7.25: It is not clear whether string->number operates on numbers with units in them. Production 78 defines number to allow units, but the description of string->number says it returns a number (not a quantity).
8.5.8: There's a superfluous space following the backslash in sentence discussing #\space.
8.5.8.1: Use of character-property-declaration and added-char-properties-declaration should require the charset feature.; Clarify treatment of redeclaration of character properties.
8.6: define-language and declare-default-language should not be part of the core expression language.
8.6.2: format-number and format-number-list are supposed to be in the core expression language.

Defects in Clause 9: Groves

9.4: The classnm property needs a cn="#all" attribute.
9.6: The public identifier for the property set DTD is missing a slash.; On syntax/slitasns the acnmprop attribute should have the value resname not refname.; On doctype/elemtps the acnmprop attribute should have the value "gi stem" not "gi rankstem".; entdcl/entity should have a when clause that makes it null when the entity is declaring a default entity.; On element/simplelk the acnmprop attribute should be linktype not linkset.; The subdcsds psmodule should depend on the subdcabs not the subdabs module.; In the lexdef for GI, the provide should be doctype not dtd.; The genents property of doctype should include those default entities that were referenced in the DTD (eg in CDATA attribute values).

Defects in Clause 10: Query language

10.2.1: A symbol should be allowed as a member of a list representing the grovepos.
10.2.3: Many of the definitions call siblings when they should call rsiblings.
10.2.4.2: Clarify behaviour of hierarchical-number, when the node does not have all the ancestors listed in the first argument.

Defects in Clause 12: Style language

12.4.1: Use of the current-node procedure in a construct-expression should not require the query feature.; The default construction rule for an ssep node should be (empty-sosofo) not (make character).
12.4.3: Clarify what happens if next-match is called when the current processing mode is different from the processing mode of the current match.
12.4.6: Use of the application-char-characteristic+property-declaration should require the charset feature.; Clarify treatment of redeclarations of properties declared with application-char-characteristic+property-declaration and character-property-declaration.; char-script-case should be optional (maybe dependent on charset feature).
12.5.1.2: Use of the procedures defined in this clause within the left/right/center-header/footer characteristics of simple-page-sequence should be handled like uses within a generate-specification.
12.5.2: There should be a (length-spec? obj>) procedure.; The prototype (/ x length-spec) should be removed.
12.5.4.1: In the description of the display-space procedure, the conditional?: keyword argument is incorrectly referred to as conditional:.; A length-spec should be allowed for any characteristic with a display-space type (just as a length is allowed for any characteristic with a length-spec type).
12.5.4.2: A length-spec should be allowed for any characteristic with amn inline-space type (just as a length is allowed for any characteristic with a length-spec type).
12.5.8: For entity-address and idref-address clarify that the entity or element addressed is in the same grove as the current node. A node identifying the grove should be allowed as an optional second argument.
12.6.2: The span characteristic is missing from display-group.
12.6.6: The specified initial value for asis-wrap-indent: is not an allowed value for the characteristic. The initial value should be 0pt.; The expand-tabs?: characteristic should be called expand-tabs: (without the question-mark). The convention is that only boolean-valued characteristics have named ending in a question mark.; Clarify interaction between expand-tabs, input-whitespace-treatment, and lines.; The initial value of last-line-justify-limit: should be 0pt rather than 0.; The line-number-side: characteristic lacks an initial value. start is the obvious choice.; The line-number-sep: characteristic lacks an initial value.; Specify that the value of the country: characteristic is the 2 letter ISO 3166 country code (as used in Internet addresses) not the 3 letter one.
12.6.7: Clarify meaning of space-after specified on paragraph-break.
12.6.9: The sideline-side: characteristic lacks an initial value. start is the obvious choice.; The sideline-sep: characteristic lacks an initial value.
12.6.11.1: Clarify that these properties cannot be redeclared.; math should not be allowed as a value for the math-font-posture character property.; inline-space-space lacks an initial value. The initial value should be the symbol #f meaning the value is whatever the font metrics say it should be (as with min-post-line-spacing)
12.6.14: The type of the length: characteristic should be length-spec not length.; The length: characteristic should be required to be specified for an inlined rule in the same circumstances as it is required for a leader.
12.6.14 (and others): The display-alignment: should allow values of page-inside, page-outside, spread-inside, spread-outside as the quadding characteristic of paragraph does instead of inside and outside.
12.6.15: It doesn't make sense to allow #f as the value of entity-system-id.
12.6.26.8: Description of initial value of fraction-bar: characteristic is misleading. It should say that the initial value is a rule with all inherited characteristics inherited.
12.6.27.3: When the table-auto-width feature is not present, it should be permitted not to specify the width for up to one of the columns.
12.6.27.1: When there is no table-cell flow object applicable to a given geometric cell, then a table-cell flow object with no characteristics specified must be implied for that cell.
12.6.27.7: If there are conflicting borders of equal priority one from a table-border and one from a cell-border, the one from the table-border should win.; If there are conflicting borders of equal priority, one with border-present?: #t and one with border-present?: #f, the one with border-present?: #t should win.
12.6.28.1: It should be clarified that the display-size of the scroll is the width of the window and the display-size for the content of the principal port is the display-size of the scroll less the size of the margins.
