Uche, using entities of any kind does not change the underlying data model. It's syntactic shugar, nothing more. The root of the problem (and a great help in other cases) is indeed the fact that any XML 1.0 document must have a single root. There are several fields where this is assumend a problem, just think e.g. of the return values of XPath or XQL expression, which rarely are single-rooted. Think how often you have heared the term "virtual root node" recently. Think of Murata's "forest automata". Forest, not tree. Guess why. However, plainly dropping the tree structure of XML is too hasty. The main problem here is the fact that there is not much between a tree and a general DAG (graph). Oodles of folks are in search for a convenient data model just in the middle of tree and graph. This would help to truly merge hyperlinks, RDF and XML. Check http://www.w3.org/TR/schema-arch Thus: entities are truely no soulution. However, so far nobody succeded in suggesting a "true" non-tree data model for XML. ++im uche.ogbuji@f... <uche.ogbuji@f...> wrote at 10 Dec 99, 8:41: > > The decision to make an XML document contain just a single element is the > > root of the problem. > > While this may be the root of other problems, and I do not claim to vouch for > all such problems, it is _not_ the root of the particular problem in question. > I see no reason why the log file must be a well-formed XML document.
