DocBook toolchain questions

[Joseph Koshy]

A couple of questions about our DocBook to PDF translation
process:

1) Is it possible to use <olink> to refer to documentation
   named by entities (say other documents) inside our
   documentation collection?  Using <ulink url=""> forces
   links to go to HTML documents.

2) I noticed that <ulink url=""> elements are getting
   rendered as "TEXT" + "URL" in the PDF document.  Why
   don't we use PDF links directly?

3) Is is possible to render <programlisting> elements with
   a smaller than default font?
