It's certainly possible to construct a regular expression, a long and complex one, that will match all IRIs and only IRIs (note that "IRI" by itself means "absolute IRI with or without fragment identifier"). The question is whether it's really worth doing so. If you feel you need it, by all means go ahead. -- LEAR: Dost thou call me fool, boy?
