Hi Abir,

Yes, the grammar of the file format is specific, just like xhtml or mathml doesn't need to match all nodes.
XHTML is an XML 1.0 which means it can contain all kinds of valid XML constructs, including entity references, CDATA, etc. I believe InkML is the same. I think unless you control the production of XML and can restrict the feature set used (for example as boost serialization does), you are really forcing yourself into a corner since you won't be able to handle all valid instances of your vocabulary.
Highly unlikely since most of the XML parsers are hand-coded.
Not sure why! I always had specific xml parsers in Antlr (the highly used language recognition tool) faster than the generic one.
It is possible that you can come up with an Antlr-generated parser for a subset of XML that is faster than the general-purpose parser. Though I still doubt it and will believe it when I see the benchmark results ;-). Of course we are talking about comparing high-performance parsers such as SAX2 here. hth, -boris -- Boris Kolpackov Code Synthesis Tools CC http://www.codesynthesis.com Open-Source, Cross-Platform C++ XML Data Binding
