That isn't what I said, no. I did not say that there were no constraints
whatsoever. I said that the specific constraint you cited was not one
that any svg tiny 1.2 element had.

If an element is constrained to point into the current svg document
fragment it is constrained to constrained to point into the current svg
document fragment. Which means it cannot point outside the current svg
document fragment. That appears to be simple logic.

If an element can point to an random location then it can point to any
random location, which includes pointing to parts of the current
document, which includes those parts both inside and outside the current
svg document fragment.

Okay, well we can certainly look at correcting that.
