And just to extend excellent George's explanation in DocBook
there are
two following patterns defined:

   db._any.attribute =
      attribute * 

   db._any =
      element * - (db | html) {
(db._any.attribute | text | db._any)* }

This means that for all elements except for elements in
DocBook (db
and HTML (html namespaces
there is a pattern matching any attribute on
such elements.

If you are defining new elements in other namespace then
DocBook and
HTML (including no namespace) you have to change definition
of db._any
to exclude your newly added namespace like:

   db._any =
      element * - (db | html |
myNewNs) {
(db._any.attribute |
text | db._any)* }

I have been bitten by this several times when I have
prepared SVG and
MathML customizations for DocBook 5 (see
http://www.docbook.org/docs/howto/#faq-customization-
mathml).
