I think you meant xslt.
It's also convenient to use xquery as expressionLanguage. It looks for
example like this:
<doc>
<a> {$var} </a>
<b> {$var2} </b>
</doc>
But as for complex invocations, it's not a good idea to pass a lot of
data between web services. You can consider using external variables
to store this info in database (for example in id, blob rows) and pass
only ids.
