So there is a SHOULD NOT prohibition against bogus colons of the
first kind (non-namespace).
Bogus colons of the second kind (namespace experiments) may
indeed have to be changed, but why must the DOM support non-W3
namespace experiments? The uses of colons in namespaces are
now prescribed, and other uses are proscribed.

You're right in general. But the XML Rec goes to some pains to say
that uses of : are either deprecated or may have to be changed,
putting people on notice pending the namespace Rec.

The alternative form <?IS10744 arch ...?> works fine;
I'll get the XAF maintainers to add support for it.

Are colons NAMESTRT characters in the reference concrete syntax?
