Well, I'd say that roughly speaking a URI can be a name, a reference,
or a source (for inclusion/transclusion).  In the first case, any URI
will do.  In the second case, we have a rough practical understanding
of what it means to dereference a javascript: URI (something happens).
The third case is problematic, but so it is for many existing schemes
like tel: and telnet:.

I make no claim to be comprehensive, but I think the burden of persuasion
is on someone who'd show that javascript: is more difficult than the
others like it.

I think I best switch to RELAX NG.
