What should the extension-element-available() function return if an
implementation of the named extension element exists, but cannot be used in
the current context because the namespace prefix is not declared in the
[xsl:]extension-element-prefixes attribute of any enclosing element?

The current spec suggests "true", but usability considerations suggest
"false", since if the extension-element is actually used in that context it
will be interpreted as a literal result element rather than reverting to the
xsl:fallback behaviour.
