According to the specs I would say that you should raise an error for
the URI as it is not legal. Ultimately this means that the user (or the
editor/tool the user is using to generate the document) should convert
the spaces to %20. Additionally, I would say that the ":" is illegal
based on rfc1738 [1] which says:
Thus, only alphanumerics, the special characters "$-_.+!*'(),", and
reserved characters used for their reserved purposes may be used
unencoded within a URL.
Under file:// there is no reserved purpose for the ":" character as I
read it.
The gray area is that Namespaces in XML and xs:anyURI talk about strings
that can be turned into URI references. In both cases however, I think
that the algorithms they cite do not allow for converting " " to "%20".
