- E01: errors in WebCGM 2.0 XCF DTD.
Date of this entry: 07 March 2007
Class: Class 2.
These are considered to be editorial errors ("minor typographical correction"). In all cases they represent either editorial deviation of one piece of DTD code from its normative repetition in another place, or else failure to update DTD code to match normatively documented functionality in another place. The WebCGM WG believes that conformance of implementations is unaffected.
Overview: There are three interrelated editorial errors (see "Bug details" below) in the external DTD file (, ) that was published on 2007-01-30 concurrently with the publication of REC WebCGM 2.0 .
The WebCGM 2.0 XCF chapter  defines a System Identifier (SI) whose associated URI is , which resides in OASIS web space. The URI  is viewed as the "latest version" URI for the DTD. It now points via a symlink to a specific version , in which you will see the error(s).
Bug details: The three-part error in the 20070130-published DTD  is:
E01.1: line 92, after "desc CDATA #IMPLIED" there is a stray ">". Proposed Correction: delete stray ">".
E01.2: line 93, the string "%linkuriAttExt;" has "Ext" capitalized instead of "EXT" upper case. Proposed Correction: change "Ext" to "EXT".
E01.3: line 43, the entity definition of "linkuriEXT" is "" instead of EMPTY. Proposed Correction: change the 2-character string "" to the 7-character string "EMPTY".
In theWebCGM 2.0 REC text , the glitches E01.1 and E01.2 are not repeated. However the glitch E01.3 is repeated in 4.3.8 and 4.4 , in the in-text listing of the DTD snippets and in the in-text complete DTD:
E01.4: section 4.3.8: in the DTD snippet, the entity definition of "linkuriEXT" is "" instead of EMPTY. Proposed Correction: change the 2-character string "" to the 7-character string "EMPTY".
E01.5: section 4.4: in the complete DTD, the entity definition of "linkuriEXT" is "" instead of EMPTY. Proposed Correction: change the 2-character string "" to the 7-character string "EMPTY".
The proposed DTD-code correction of the errors E01.1-E01.3 above is found in the file :
This is the proposed DTD correction file of the coordinated OASIS errata processing. The actual DTD file that is ultimately approved will be the result of coordinated W3C and OASIS errata processing.
Two changes to the text of WebCGM 2.0 REC are also proposed, as specified in E01.4 and E01.5 above.
