I agree, a pity. It is correct though, XHTML 1.1 has no reference to
xml:base at all, but a very clear definition of "/html/head/base":
So while @xml:base is off limits for RDFa in XHTML 1.1, it seems
reasonable to treat the value of base/@href in the same way (as if an
@xml:base with that value was present in the root html element).

Does this seem correct?

(In XHTML 2 though, @xml:base is available everywhere, so resolving
how to treat that is still relevant in the future.)

Best regards,
