The XHTML 1.0 strict DTD as shipped with XHTML 1.0 spec REC-xhtml1-20000126 (which also carries this revision info: $Revision: 1.14 $ $Date: 2000/01/25 23:52:20 $) has some hygenic problems which emit warnings during validation. To wit, a perfectly valid document will cause it to emit these warnings: > onsgmls -wxml -wall -s xhtml-1.0-strict.xml onsgmls:/usr/lib/sgml/dtd/xhtml-1.0/xhtml1-strict.dtd:97:0:W: unused parameter entity "MultiLengths" onsgmls:/usr/lib/sgml/dtd/xhtml-1.0/xhtml1-strict.dtd:166:0:W: unused parameter entity "focus" onsgmls:/usr/lib/sgml/dtd/xhtml-1.0/xhtml1-strict.dtd:885:0:W: unused parameter entity "CAlign" onsgmls:/usr/lib/sgml/dtd/xhtml-1.0/xhtml1-strict.dtd:88:0:W: unused parameter entity "FrameTarget" onsgmls:/usr/lib/sgml/dtd/xhtml-1.0/xhtml1-strict.dtd:844:0:W: unused parameter entity "TAlign" Proposed remedy: Apply the attached patch to the DTD, which fixes the problem (and also actually makes the DTD a bit smaller, by actually taking advantage of the %focus parameter entity). Rationale: It's disorienting to the user who is fastidious enough to check all warnings against their document to find that the DTD itself has some hygenic problems. Please let me know if this information is useful -- I can go through the rest of the XHTML 1.0 DTDs and correspondingly check and scrub those as well. -- .....Adam Di Carlo....adam@onShore.com.....<URL:http://www.onShore.com/>
