This is a document-centric view of XML and not a data-centric one. If I have
XML in a database and I modify it, there should be a way to make sure the new
document conforms to the database schema. If hierarchical, relational and
object databases can give me this functionality I see no reason why a native
XML database should not.

THINGS TO DO IF I BECOME AN EVIL OVERLORD #19
I will not have a daughter. She would be as beautiful as she was evil, but
one look at the hero's rugged countenance and she'd betray her own father.

Subject: RE: [xml-dev] XMLSchema validation during an Update
Nice one. Well, truth is people have a very 'static' view of XML.
But the more I work with the markup, the more I understand that
"documents" do not have as much meaning as they used to.
Oh well.
The easy answer is that validation has no place during any operation on
the document. It is supposed to happen when you
load/receive/send/whatever your markup, not while you are modifying it.
The other answer is that if you want constant validation (a hypothetical
impossible nightmare) you should validate types, not documents.
Kindest regards,
Manos
