partial XML editing

The XML Schema 1.0 spec. defines how to bind an instance document
and a schema, for editing applications.

Suppose the following case : you want to build an XML editing
application to edit an XML document against a Schema, BUT
you may want te restrict the nodes to be edited (like in a
common formular), in other words partial editing.

In that case, it would a programming overloading to acquire all
the schema information to just edit a small part.

So the question is whether that case is relevant to the Schema
standard or of the implementation ?

I don't have a clear idea.

Comments are welcome.
