I am using an XML schema to check (validate) the structure of an XML
document. But since I cannot check everything I need using a schema, I
am thinking of using XSL for more detailed checks (value comparisons
etc.) in a second step.

Validation using an XML schema is pretty straight forward: I simply
define the schema document when parsing the XML to a DOM model in my
Java code. Any validation problems comes out as exceptions (which I know
how to handle).

But how do I generate exceptions when applying XSL to my document? I.e.
how will I be notified that some conditions (that I defined in the XSL
document) are false? I guess what I need to know is how to use XSL as a
validation tool in a Java application.

Any advice, links etc would be much apprechiated.

Schematron is a schema language that allows you to make certain
assertions and then check them using an XSLT 1.0 processor:

Not sure that is what you are looking for but check that out yourself.
