To explain the difference between what is available now, and what we
mean by XSLT 2.0 working directly against the database, think of this
example:

- You have 1000 xml files stored in the database, and each of them
have a <title>
- You want to get those titles and group, sort and number them using xslt 2.0
- Currently you either a) use xquery to get the title nodes, wrap them
in an arbitrary root element, then supply that document to the
transform (which needs to know about that new document) using the
database's xslt extension, or b) access all documents using say the
rest api and then extract the <title> from within the xslt...  not
very feasible, and not taking advantage of the database.
- When xslt can work directly on the database, you would just do
<xsl:for-each-group select="collection(...)//title">
