XML xpointers in SDQL

[James Clark <jjc@xxxxxxxxxx>]

ftp://ftp.jclark.com/pub/test/xpointer.zip is an implementation of XML
xpointers in SDQL.  This works with Jade 0.7.  It doesn't exactly follow the
current draft (notably it doesn't count pseudo-elements), and some features
are not implemented (eg wildcards for attribute names, spans).  There's also
a tiny SGML document and DSSSL style sheet that exercises this.  Since Jade
currently only supports a single input document this probably isn't yet very
useful, but I thought people might find it interesting.
