__cmwc_t URIs should be absolute too?

[thomas-fossati]

Allowed types for __cmwc_t values are:

• absolute (i.e., non-relative) OIDs
• URIs

Note that a (URI) relative reference can be any string (more or less), including the empty one.

Besides, a relative OID in dot-decimal notation (e.g., .2.3.4) parses OK as a relative reference, making the restriction we put on OID a bit moot.

Thirdly, it is completely undetermined what URI would be the base to resolve a relative form.

For these reasons, I advise we make URIs absolute too.

Agreed.
