It seems  the use of  SVG (scalable vector graphics) as an alternative
to  GIF, PNG and JPEG images  (for which by the way we have
an external parser which we are currently testing) is gathering
momentum.

SVG is of course  XML, and can be indexed using standard XML
parsers. Can I ask if anyone is using  htdig with such an external
parser? If so, which one? 

May I also ask the developers what their long term plans are
to allow htdig to define schemas for  external files in  XML?
It might make sense for example to implement the XHTML
schema into  htdig?  I presume that is a gargantuan task
however! 

With a schema (much like  IE 5.0/5.5 also allows an  XML
document to be validated against a defined schema) one can 
parse internally, rather than invoking external parsers. The
Apache XML initiative is producing some wonderful generic
XML tools, and one wonders whether htdig could make use
of any of them.
