>> EQname: QName | UriLiteral ':' NCName   /* ws:explicit */

In many ways this suggestion is attractive. However, there is one context where
it wouldn't work well:

<xsl:value-of select="key('my:key', 1234)"/>

<xsl:value-of select="system-property('my:operating-system', 1234)"/>

<xsl:if test="function-available('my:function')"/>

Replacing the lexical QNames here by an EQName as proposed here would require
use of escaped quotation marks (&quot;), which is unappealing.

So perhaps we should adopt this, but also introduce backtick as a third kind of
quotation mark for use in all contexts where we currently allow paired
double-quotes or single-quotes? Or perhaps just as a third option for a

An alternative would be to use a different format (such as {uri}local) for
run-time QNames, but that's not nice either.
