*TC Policy

Work item code:

Category:

* B (Addition of feature)

Reason for *
change:

The WFS 2.0 spec requires that coordinate reference systems referred
to in WFS interactions be identified by OGC URNs. Current OGC policy
is to _allow_ URNs, but to _recommend_ http URIs (URLs).

Summary of *
change:

Modify the relevant clauses to allow http URIs with the pattern
http://www.opengis.net/def/crs/[epsg|ogc]/0/{code}
for identification of CRSs.
The XML schemas do not need changing, as the relevant references are to xs:anyURI
