He mentions VML almost right out of the gate, here didn't he? "I have followed the standards for XML-based vector graphics closely. PGML (mainly from Adobe) and VML (mainly from Microsoft),"
Thanks. Yeah I didn't really see VML as relevant after its very inception. True it was sitting there in IE for an extra decade or two but it never had some sort of resurgence or potential that I saw. Silverlight on the other hand had serious people saying "this is the future!" When VML first came out, it had to be taken seriously. Next to PGML, not so much.
