Quick reference card developed by Mulberry Technologies in PDF format

The site gives a reference of all elements in the W3C spec, detailing which implementations support the feature. The site focusses on MSXML (the most easily available implementation for VB programmers). The reference links to examples with the results generated by several implementations (Saxon, XT, Xalan, MSXML). This allows to compare implementations side-by-side.
