Okay, fair enough.  So SVG allows a subset of what XLink allows: nothing
amiss with that.

I think there is a huge difference between extending and subsetting.
You are already subsetting XLink by using simple links only (indeed,
the Core WG is considering making simple-links-only a formal conformance
level of XLink 1.1).  So disallowing LEIRIs that are not IRIs, which
you are already doing implicitly, is perfectly fine.

Arise, you prisoners of Windows / Arise, you slaves of Redmond, Wash,
The day and hour soon are coming / When all the IT folks say "Gosh!"
It isn't from a clever lawsuit / That Windowsland will finally fall,
But thousands writing open source code / Like mice who nibble through a wall.
