SXML in Emacs

Hello!

I am working on an XML parser framework, much inspired by SSAX, for
GNU Emacs. An important part of this will probably be an XML->SXML
parser.

I am going to have a couple of questions regarding the SXML standard,
but right now a particular problem is of more concern for me:

For my XML processing tasks I need a data structure that allows to
keep the contents of a text-node in an Emacs buffer, as an alternative
to keeping them only in Lisp strings.  The plan is to have a unique
Lisp object denoting a text node which contains a reference to the
buffer holding the text.  The according text in the buffer in turn,
will have this object in a text property.

Obviously this would require an extension to SXML.  Since this is
very Emacs-specific, I guess that shouldn't be a problem.  However, I
am asking here to get some opinions.

I imagine something like this as an alternative to a string in an
SXML document:

(*TEXT* <buffer> <parent-element>)

With <buffer> being the Emacs buffer holding the text (which a program
would then extract by searching for the right text property). And
<parent-element> being a back-reference to the containing element.

Any thoughts? Or is SXML just not the right thing for me?  I have no
particular need for it myself, but I fancied that it would be nice for
users to have a somewhat standard s-expression representation.
