Historically the W3C have had great difficulty in defining what a URL/URI was. the XSD 1.0 definition had some ... features, and XSD 1.1 redefined it to have the same value space as xsd:string (with the intention that you can use it with natural strings documents and any uri-encoding is done as some back end process cf a browser address bar.)
most of our existing cds have
<CDURL> http://www.openmath.org/cd/arith1.ocd </CDURL>
and the schema says
CDURL = element CDURL { xsd:anyURI }
so this matches or not depending on the built in anyURI definition.
Of the ones I have to hand rnv and xmllint says it is valid and emacs nxml mode says it is not
I don't really want to change the schema to make space explicitly allowed (doing that while referencing anyURI is a bit convoluted I think) and the schema is anyway in the openmath spec, so I suggest I just do a global edit and remove the space from xsd:anyURI elements. (I never liked those spaces anyway:-)
