Schema constraints

[Pascal Maugeri <pa...@gmail.com>]

Hi

I have read in the user guide:

"This means it does not have any schema that constrains what can be
placed into a document collection."

Does it mean that the external app has the "responsability" to verify
the schema ?

Another question: how to search for XML documents that implement a
given XML schema ?

Regards,
Pascal

Thank you for your answer Vadim.

FYI, I would not dare to provide a patch to Xindice yet due to my poor
knowledge of Xindice itself and XML/XSD in general :-))) I will stick
for the time being to my role of humble user.

Xindice does not care about DTDs or XSDs at the moment -- you can put any 
document you want. So if you want to validate the document against DTD or 
schema, do that before you store it in a database. Next version of Xindice might 
support validation -- and it will happen sooner if you provide a patch :)

(Hmm... I'm not even sure you can put document with DTD into Xindice -- I recall 
the were some issues with it... Anybody else remembers?)

If it can be done via XPath [1], it should work in Xindice. I'm not sure though 
if it's possible.
