RE: IRI-Everywhere

(more on spaces in IRIs).


An observation I have not seen is that anyURI limits spaces significantly
with the rather obscure constraining facet whiteSpace=collapse. (I hadn't
notice this until now).

This means that an anyURI does not:
- start with a space
- end with a space
- contain double space inside it
- contain #xA #xD or #x9

The IRI in namespaces 1.1 allows for all of these possibilites (possibility
not the first, since namespace IRIs have to be absolute.)

I am not sure what the IRI draft permits.
