XML catalog nextCatalog/@catalog documentLink support.

[angelozerr]

Given this XML catalog:

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">

  <nextCatalog catalog="plugins/org.dita.base/catalog-dita.xml"/>

</catalog>

This sample comes from catalog-dita.xml from https://github.com/dita-ot/dita-ot/releases/download/3.5.1/dita-ot-3.5.1.zip

It should be nice to have hyperlink for nextCatalog /@catalog attribute

I would be interested in working on this. Ideally, all the elements that refer to another catalog (have a catalog attribute that's a URI) that are defined in the catalog schema should have document links. These are:

• delegatePublic
• delegateSystem
• delegateUri
• nextCatalog
