Subject: RE: [dita] DITA 1.1 issue 20: Extensible metadata attributes


Epic handles both DTDs and XML Schemas. When using a DTD,
any prefixed (namespaced) attribute not declared in the DTD is
allowed.
 
Namespacing attributes is an easy way to allow arbitrary attributes
to be added without having to modify the DTD or schema and, at
the same time, to make it easy to recognize and provide special
processing for a certain set of attributes.

Isn't Epic's DITA support still DTD-based? How would namespacing extensions to %select-atts; help in DTD-land?

I haven't thought a lot about this yet, but I was having
a discussion with some of our developers today who also
felt the need for extensible metadata attributes, and 
they felt the right way to do it was to have a separate
namespace for metadata attributes.  

Then the DITA schema could allow any attribute in
that namespace on any element, so it would be easy 
to add "profiling" attributes or other metadata.

Could I get an idea from our XML gurus how this could be 
achieved in a 
compatible manner? The issues list does not quite have a lot 
of details.
