If I load a schema for documents then I presume I can start doing things like
If( $f/@start_dt lt $f/@end_date )
without having to do
If( xs:dateTime($f/@start_dt) lt ($f/@end_date ) )
That would be really nice.
Couple questions.
Do I have to "validate" the documents in order to pull in the schema
information ?
As in
http://www.w3.org/TR/xquery/#id-validate
and if so where do I need to do this ? when I first load the doc ? On any
references in functions with nodes ?
Do I need to store an xsi:schemaLocatio in the document or will ML magically
find my schemas by namespace ?
Finally ... is there a general rule about the overhead this incurs ? Obviously
it can be 'free' but I could imagine cases where due to type caching that using
a schema may be more efficient then lots of manual casts ... and certainly
helps with tightening up method signatures and cleaning up expressions.
Any short "these are the easy tips" docs to read ?
Thanks
