My question was more specific: what are the *techical differences*
betwen LEIRI and Web Addresses?
Can't we have one technology instead of two?

Unfortunately, languages outside HTML5 (notably XLink, XML Base, SVG,
XForms), that use W3C Schema definition and anyURI type, use exactly
Other technologies instead use pure URI / IRI (XMLNS, RDF) and I
wouldn't see much benefit in relaxing their syntax (because they never
actually process their identifiers).
