Foreword

Technical Corrigendum 1 to International Standard ISO/IEC 15445:2000 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC34, Document description languages. JTC1/SC34 has worked on this project in close cooperation with the World Wide Web Consortium. This International Standard makes normative reference to the W3C Recommendation for HTML 4.

Introduction

This Technical Corrigendum

It makes normative technical changes to the International Standard, altering the requirements and recommendations for the use of the W3C Recommendation for HTML 4. These changes result in part from practical experience with the language defined by the International Standard and in part from the World Wide Web Consortium's adoption of HTML 4.01 as the reference specification for the HTML 4 language.

Changes

1 Latin alphabet No. 1 entity set public text description

Add the following text into annex B:

The DTD defined in this clause references the entity set specified by the W3C to define the characters of ISO 8859-1 8-bit single-byte coded graphic character sets — Latin alphabet No. 1. The reference uses a formal public identifier ``-//W3C//ENTITIES Full Latin 1//EN//HTML'' which contains the public text description ``Full Latin 1''. The public text descriptions ``Latin alphabet No. 1'', ``Latin 1'' and ``Latin1'' are permitted alternatives which describe the same entity set.

NOTE: The User's Guide to this International Standard describes a way in which system administrators may allow simultaneous use of these alternatives.

2 Symbols entity set public text description

Add the following text into annex B:

The DTD defined in this clause references the entity set specified by the W3C to define mathematical, Greek and symbolic characters. The reference uses a formal public identifier ``-//W3C//ENTITIES Symbolic//EN//HTML'' which contains the public text description ``Symbolic''. The public text description ``Symbols'' is a permitted alternative which describes the same entity set.

3 Simultaneous ID and NAME attributes

In annex B, part 1, parameter entity core, generic attributes, replace the comment text with the text:

The name space of the ID attribute is shared with the name space of the NAME attribute. Both ID and NAME attributes may be provided for the <A> [W3C12.2] and <MAP> [W3C13.6.1] elements. When both ID and NAME values are provided for an element, the values shall be identical. It is an error for an ID or NAME value to be associated with more than one element in a document.

It is recommended that authors of documents specify both the ID attribute and the NAME attribute for the <A> [W3C12.2] and <MAP> [W3C13.6.1] elements.

In annex B, part 3, attributes for element type <A> [W3C12.2], replace the third paragraph of the comment with the text:

It is recommended that authors of HTML documents specify both ID and NAME attributes. When both attributes are specified, they shall have identical values.

In annex B, part 3, attributes for element type <MAP> [W3C13.6.1], add a second paragraph to the comment with the text:

It is recommended that authors of HTML documents specify both ID and NAME attributes. When both attributes are specified, they shall have identical values.

4 Accessibility of client side maps

In annex B, part 2, the declaration of the element type <MAP> [W3C13.6.1] is changed to:

<!-- Authors should use the block-level content of the <MAP> element when
     creating accessible documents.  Each region should be specified using
     an <A> element to define its associated link and shape.  User agents
     should render the block-level content of a <MAP> element. -->
<!ELEMENT MAP         - -  ((%block;)|AREA)+ >

In annex B, part 3, the attribute definition list of the <A> [W3C12.2] element type is extended with the addition of the attribute definitions:

    COORDS     CDATA      #IMPLIED -- Comma separated list of values --
    SHAPE      %shape;        rect -- Control interpretation of coords --

In annex B, part 3, attributes for element type <A> [W3C12.2], add a fourth paragraph to the comment with the text:

COORDS shall not be specified if SHAPE has the value `default'.

5 HTML 4.01

Change all references to the `W3C Recommendation for HTML 4.0' to `W3C Recommendation for HTML 4.01'.

Remove the words `amended by the HTML 4.0 Specification Errata' from the fifth paragraph of the Foreword.

Remove the words `amended by the HTML 4.0 Specification Errata' and the first note from clause 3, Normative references.

6 FORM content model

In annex B, part 1, the declaration of the parameter entity %form.content; is removed and the declaration of the parameter entity %text; is changed to:

<!ENTITY % text '#PCDATA | %physical.styles; | %logical.styles;
                         | %special; | %form.fields;' >

In annex B, part 2, the declaration of the element type <FORM> [W3C17.3] is changed to:

<!ELEMENT FORM - - (%block;)+ -(FORM) >

In annex B, part 2, the declaration of the element type <FIELDSET> [W3C17.10] is changed to:

<!ELEMENT FIELDSET - - (#PCDATA,LEGEND,(%block; | %text; | ADDRESS)+)
                             -(FIELDSET) >

In annex B, part 2, the declaration of the element type <LABEL> [W3C17.9.1] is changed to:

<!ELEMENT LABEL - - (%text;)+ -(LABEL) >

In annex B, part 3, attributes for element type <BUTTON> [W3C17.5], add a seventh paragraph to the comment with the text:

The <BUTTON> element should be used only in the content of a <FORM>
element.

In annex B, part 3, attributes for element type <INPUT> [W3C17.4], add a ninth paragraph to the comment with the text:

The <INPUT> element should be used only in the content of a <FORM>
element.
