SRS handling questions

[Martin Schulze]

Hi,

I wonder how I should interpret the WMS specification with regards to
SRS handling.

The specification [OGC 01-068r3, §7.1.4.5.5, page 26] says about
inheritance of SRS:

 - Every layer shall have at least one SRS element that is either
   stated explicitly or inherited from a parent layer.

 - Layers may optionally add to the global SRS list, or to the list
   inherited from a parent layer.

Since the specs don't lose a word how these two cases are
distinguished, I'd consider them clashing.

Does anybody feel I should not implement the first rule and skip the
latter?


Also, since the XML response has both <SRS>foo</SRS> and
<BoundingBox SRS="foo" minx=...> elements, I wonder if it wouldn't be
wiser to extract information about availibl SRS from the <BoundingBox>
element, except for the root layer.

I'd say yes, but I'd better ask if somebody sees a problem with this.

Regards,

	Joey
