[georss] GML georss namespace

[Knoth, Brian D.]

Great, so it seems we agree on the georss application schema - namely,
that it should probably be updated to reflect correct namespace, etc...

I did not mention anything about RSS validation and binding, but since
you've brought it up, I'm curious as to why you think it is a bad idea
and why it would cost someone down the road. I would think that as more
machine processing of RSS occurs (such as Yahoo Pipes), that schema
validation and bindings become more important. Atom has a schema and
that does not seem to have impact on the extensibility of that
syndication language.

I agree that the schema needs to be updated to support xml validation
and xml binding (via .NET, JAXB, XMLBeans, etc.)

However, I agree with Gregor - schema bindings and validation for rss
is a bad idea - it's going to cost you down the road...

If you need a Java-based parser check out
http://www.kartographia.com/geoRSS/ 

It's DOM based and is very loosely bound to the underlying schemas
(GeoRSS, GML, Atom, and RSS).

good catch. i have never seen /10 in the wild, so it is safe to say
that 
the schema is wrong. while it would have been a good idea to version
the 
xmlns, that ship has sailed.

i very much doubt it. one of the highest quality parsers on any
language 
is called ultra liberal feed parser in recognition of the sorry state
of 
most rss feeds out there.

http://feedparser.org/

in light of that, i don't think xsd validation is a viable strategy,
sadly.
