fix the reported CRS identifier when the CRS84 alias URI is requested#567
Merged
Conversation
When a request references CRS84 by its registered alias URI http://www.opengis.net/def/crs/OGC/0/CRS84, the CRS of the response (e.g., in the Content-Crs header) was reported with the primary URI http://www.opengis.net/def/crs/OGC/1.3/CRS84. OGC API Features Part 2 requires that the CRS identifier used in the request is echoed. - EpsgCrs: new auxiliary attribute uriOverride, excluded from equals()/hashCode(); toUriString() returns it when present. Instances that differ only in the URI used to reference the CRS remain equal everywhere (supported-CRS checks, transformer caches, CRS84 special cases). - OgcCrs: new constant CRS84_OGC0, the same CRS as CRS84, but with the alias URI as uriOverride; fromString() returns it for the alias spelling. - EpsgCrs: toAlternativeUriString() replaced by allUris(), which lists all registered URIs of a CRS (the canonical URI plus, for CRS84, the alias URI).
