In the XSLT 2.0 Working Draft 4 April 2005,
http://www.w3.org/TR/2005/WD-xslt20-20050404/, the Note paragraph in section
"3.11 Embedded Stylesheet Modules" says the following:

"In order for such an attribute to be used with the XPath idFO function, it must
actually be declared in the DTD or schema as being of type ID. The same
requirement typically applies if the identifier is to be used as a fragment
identifier in a URI reference."

According to my knowledge an attribute must be typed to be of type ID. The
paragraphs says that the type information MUST be supplied via a DTD or schema.
However, according to my knowledge there is another mechanism for adding ID type
information: xml:id. In the similar vene, from what I know one could argue that
a DTD is a particular type of schema.

In order to not constrain the user's possibilities and be open to future
developments in the typing-area, it might be of interest to phrase the paragraph
more generically, to only dictate that the attribute needs to be of type ID, and
to give DTD as an /example/ of how to express that type information. According
to my interpretation, it would be normatively wrong to accepttype information
expressed via xml:id.

However, considering the controversies over xml:id, this is perhaps intentional.


Cheers,
