dia-shape-ns

Sorry if these questions have been answered -- I'm new here, and 
haven't seen them answered in the archive. 

1.  I'm wondering if the name space definition from the dtd's found in 
the doc directory of the distribution exist somewhere?  It is currently
coded as "http://www.daa.com.au/~james/dia-shape-ns"; which is not 
accessible.

2.  Could someone comment on the differences in svg files used by
and exported by dia versus the W3C draft?  I would like to try building
a set of custom shapes but would like to build/validate them against a
DTD
or schema in XML-spy to make sure they are kosher.  Articles elsewhere
in
the archive seem to imply that dia accepts a subset of svg, but what 
subset?  (Again, I apologize if this has been answered.  Perhaps it 
is a candidate for the FAQ or the documentation.)

3.  In my trip through the list archive, I noticed several queries about 
Visio interchangeability.  This posting might be interesting to some:

"Microsoft Corporation has released a new version of its Visio 2002 
drawing and diagramming software to manufacturing companies with new 
XML capabilitiesand support for Component Object Model (COM) add-ins. 
"Based on Extensible Markup Language syntax, the XML for Visio format 
allows developers tocreate tools for searching and indexing, revision 
tracking, and version control. This  new format gives Visio data 
synergy with new Web tools, better archival data format, and an open 
exchange of Visio data with other XML-enabled applications. XML for 
Visio is capable of describing Visio data with as much fidelity as VSD 
format, and is intended to provide open access to data in Visio and to 
enable more open exchange of Visio data with other applications. In 
addition, by using the 'Save as Web Page' feature, users can publish 
Visio drawings to the Web and at the same time generate a XML for Visio 
file that will permit round-tripping-re-opening the file in Visio 
without loss of data..."
