This also raises the issues around collections in general mapped out in
the strawman.

What is the goal of the pois collection wrapper?

Perhaps it would be better if we just started at the more granular level
of the poi then clarified the use cases for the collections.

I think it's important that an individual poi can have a unique URL
based ID - effectively making this a permalink or similar.  This then
relates to the POI/language points in this thread.

However, if we do wrap a collection of poi in a pois tag then we should
think about what else the existing Mobile AR formats also allow in terms
of meta information added at this top level.  KML, Layar, etc.  This is
kind of similar to the DOM based head/body separation in HTML and is
very useful.

If the collection is designed for responses to Queries then it should
probably at least support pagination related meta data.

If the collection is designed for local serialised storage then
cache/created/modified data would be useful.

Lots of other options here based on the use cases.

We certainly don't want all those transmitted on every request for the POI , and absent a service call specifying the language to use, we don't have another way to be concise. Maybe something in the HTTP request header to do this?
