I am quite new to XML and initially got quite excited about the XML Schema
proposal. However, reading this list there seem to be two views of what
schemas are for and I am not sure whether a schema is what I need.
On the one hand are people who do not like the totally different syntax
used in a DTD and would like to replace it with a schema which uses the
same syntax as the rest of an XML document but otherwise does the same
as a DTD.
On the other hand there are those who want to do things a DTD cannot, such
as object inheritance (<archetype> and <refines>) or reintroduce the
potentially
useful but apparently tricky "&" connector.
There is then the issue of backward compatibility between a schema and
XML 1.0. Translating a schema based document to a DTD based one can be:
possible, possible with loss of information, or just impossible.
Some want one, while some want another.
Is this a fair summary of the situation or have I got quite the wrong
end of the stick?
