Hi Isabelle,
As you found, XSLT processors handle wellformed documents as well as valid
documents.  When you add the infoid attribute, your documents may still
process, but they would fail a validation step.  If you open such a document
in a validating XML editor application, for example, it will complain.

You can easily extend the DTD by specifying a new 'common' attribute in the
internal subset of the DTD in your documents, like this:

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.4//EN"
                    "http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd";
[
<!ENTITY % local.common.attrib "infoid  CDATA  #IMPLIED">
]>

A list of discrete values (without the description) would be implemented
like this:

<!ENTITY % local.common.attrib "infoid  (changed|added|deleted|off)
#IMPLIED">

You can also replace #IMPLIED with a default value.

The %local.common.attrib; parameter entity is declared in the DTD as empty,
ready to be filled in for a customization like this.
