I like to recommend that people follow two conventions that make
namespaces less onerous:
1) don't prefix elements; change the default-prefix binding; and
2) don't use QNames in content.
Unfortunately ... two of the most significant and often-used XML
technologies, XSLT and XSD, pretty much can't be used without breaking
both principles.
And that's the problem with all of the proposals for cleaning up
namespaces. XSLT and XSD, taken together, represent an enormously
powerful set of tools for a variety of use cases. Unless you can
specify and write transformation and data-validation tools of
approximately equal power for the namespace-repaired XML variant, your
variant's a non-starter.
