Earlier this week I ferreted out most of the current XML specifications from the W3C site. I say “most” because I didn’t take the time to run down XML “related” standards such as SVG, etc. At some point I will spend the time to track down all the drafts, prior versions, and related materials.
But, for today, I have packaged up the fifty-eight (58) current XML standards in 58XMLRecs.tar.gz.
BTW, do realize that Extensible Stylesheet Language (XSL) Version 1.0 and XHTML™ Modularization 1.1 – Second Edition have table of contents only versions. I included the full HTML file versions in the package.
You can use grep or other search utilities to search prior XML work for definitions, productions, etc.
Do you remember the compilation of XML standards that used the old MS Help application? The file format was a variation on RTF. Ring any bells? Anything like that available now?
