Hardly beyond the state of the art. I've suggested in
http://www.rddl.org/fragment-syntax that support for XPointer schemes might
be indicated in a RDDL document (one which might be dereferenced from the
XPointer scheme namespace for example) e.g.

<div id="xpointer">
 <rddl:resource
   xlink:arcrole="http://www.rddl.org/fragment-syntax#scheme"
   xlink:href="http://www.w3.org/TR/xptr"
   />

</div>

Now it should be straightfoward to add pointers to various language
implementations of XPointer scheme dereferencing mechanisms via something
like:

<div id="custom-scheme">
 <rddl:resource
   xlink:arcrole="http://www.rddl.org/fragment-syntax#scheme"
   xlink:href="http//example.org/custom-scheme-description"
   />
<rddl:resource
   xlink:arcrole="http://www.rddl.org/fragment-syntax#scheme-implementation"
    xlink:role="http://www.rddl.org/natures/software#java"
   xlink:href="http//example.org/custom-scheme.jar"
   />

</div>

or whatever, this could be done in a variety of ways.
