Bug#183728: dia: DTDs should be registered

[Roland Stigge]

Hi,

I read the Debian XML Policy (Working Draft), and noticed that there are
some problems when registering the dia DTDs with our XML/SGML catalogs:

* Dia files usually don't carry a DOCTYPE declaration so DTDs in the
catalogs won't probably be useful

* Dia upstream doesn't ship catalog files (this could be worked around,
but unfortunately, there is also the next point...)

* There are no PUBLIC or SYSTEM identifiers known for diagram.dtd,
shape.dtd and sheet.dtd, so I don't know what to write into the local
catalog file. There are xmlns ids known but those are not necessarily
related to the former ones.

Therefore, the registration will be deferred. But feel free to help
here.

I will talk to upstream to improve the situation.

Thanks.

bye,
  Roland
