Well, if it were an arbitrary subset, that might be a problem.
(A very bad example would be allowing a subset of IRIs that e.g.
excluded Cyrillic and Thai.) But restricting yourself to IRIs
is not a problem at all. XML, XLink and XBase would most probably
restrict themselves to IRIs proper if it had not been for the fact
that for some years, they used a circumscriptive definition of
what would become IRIs. This circumstriptive definition is some-
what wider than IRIs, and they don't want to run the risk that some
users, or some other specification out there (e.g. something like
SVG) was actually making use of some of the additional characters
that are allowed in LEIRIs but not IRIs. As SVG doesn't have that
problem, and as all of the characters allowed in LEIRIs but not IRIs
are in one way or another problematic, SVG is perfectly fine with
IRIs.
