Hi Daniel: Thank you for your response. >Your technology seems mostly related to >the traversal of large graphs of object while our draft focus >on extracting a fragment from an existing (possibly large) XML >document. Traversal and extraction are related as follows: Whatever the traversal specification traverses in the given object graph belongs to the extracted object. I see the following correspondences between your terminology and ours: fragment context specification traversal specification XML document object DTD class graph -- Karl >From veillard@tux.w3.org Thu Jul 1 10:35:31 1999 >Date: Thu, 1 Jul 1999 10:35:18 -0400 >From: Daniel Veillard >To: Karl Lieberherr >Cc: pgrosso@arbortext.com, dem@ccs.neu.edu >Subject: Re: XML fragments and traversal specifications > > Hi Karl, > > I'm sorry for this late reply, I have been burried in other stuff in the >meantime. > >On Fri, Jun 18, 1999 at 12:55:22PM -0400, Karl Lieberherr wrote: >> Hi! >> >> I read with great interest your page: >> >> http://www.w3.org/TR/WD-xml-fragment > > Note that an updated version has been released yesterday, changes are minor >and described in appendix F.2. > >> where I found the following abstract: >> >> The XML standard supports logical documents composed of possibly several >> entities.
