[Bug 4546] [XSLT] testing for namespace axis support

http://www.w3.org/Bugs/Public/show_bug.cgi?id=4546

Proposed text: in 16.6.5, after the list of required system properties, add:

In addition, processors MAY support the following system property in the XSLT
Namespace. A processor that does not support this property will return a
zero-length string if the property is requested.

*  xsl:supports-namespace-axis, returns the string <code>"yes"</code> in
the case of a processor that offers the XPath namespace axis even when not in
backwards compatible mode, or <code>"no"</code> otherwise. Note that a
processor that supports backwards compatible mode must support the namespace
axis when in that mode, so this property is not relevant to that case.
