No longer awkward - for some uses, and they become 100% totally
completely broken for other uses.  Win some, lose some.

(1) get consensus that the broken cases don't matter (e.g. the people
who dereference a namespace URI to get a GRDDL file to find a Schema)
(2) change all existing XML systems to accept your new usage instead of
raising an error. This includes...

[1] buy everyone a new television
[2] buy everyone a new VCR (TVs and VCRs use uPNP in XML to find each
[3] replace everyone's mobile phone
[4] replace iPods
[5] re-engineer air traffic control systems, aircraft navigation...
[6] replace people's washing machines, and other XML-communicating
[7] change all Web Services
[8] replace all Microsoft Windows, Gnome, KDE, OS X, desktops
[9] car components (brakes, tyres, engines,...) communicate with XML...
[9] (many more examples)

This is why XML does not in fact get changed very much...
