The trouble is that URI and URL is used both generically (as intent of
the thing: a locator or identifier) as well as specifically (as a
syntax.) It is better to use "URI" and "URL" and "IRI" to mean the
specific syntax, and to use a more generic term, such as "system
identifier" or "resource location" depending on context, where possible.

xsd:anyURI was intended to allow any kind of URI in any syntax. It sets
the value space rather than the lexical space.

So using XSD, if you made types for URIs and IRIs they should be derived
types from xsd:anyURI, with restrictions on lexical facets only.
