RE: [xml-dev] Feasibility of "do all application coding in the XML languages"?

It would be good for the XSLT language, and perhaps others,
if a general mechanism for generating a parser was possible.  
I was at a loss to think what that mechanism might be, but I see 
you are describing one such approach taken by OmniMark.

I'm certainly not against paying for tools!  But to help XSLT 
gain traction it is necessary to make something generally useful 
available for free.  Maybe more free stuff will be available if 
the base of users gets bigger.

I like the idea!  Kind of like the text-to-spreadsheet wizards you
see, only any given (binary) thing to XML (well maybe SAX events).
