Yes. More specifically, SVG 1.1 gets XLink from XLink 1.0 and SVG Tiny 1.2 gets XLink form XLink 1.1.

It sounds as if you are saying that SVG should specify a subset of what XLink and XML Base allow. So we say they accept an IRI. 

Which is simple, but then we catch flack for embrace-and-extend (well ok embrace-and-subset).

Or we could specify differently for content conformance (IRI only) and processors (LEIRI). Not very nice either.
