  In a nutshell:
    - libxml will initiate XML Catalog searches from /etc/xml/catalog
    - Catalogs can (should) be split as a hierachical tree
    - the xmlcatalog tool from recent versions allows to manipulate
      (build/modify/test) XML Catalogs
    - the Catalog doc page covers the technical bits
      http://xmlsoft.org/catalog.html
    - there is an example for DocBook 4.1.2 XML catalogs at
      ftp://xmlsoft.org/test/dbk412catalog.tar.gz
    - the spec is at OASIS, and it simply works
      http://www.oasis-open.org/committees/entity/spec.html
      it is relatively short and readable, enjoy it !
