Right... and actually that's probably the only way to provide full custom
diagnostics in a case where you have more than one required parameter, because
with @required="true" the first missing parameter will trigger a run-time error
and the subsequent ones won't be checked.
So it's probably not that useful a potential feature to enable a custom message
on error for required stylesheet parameters.

Make the param not be required and then check for it in a root template.

Given a stylesheet parameter <xsl:param name="somevar" required="yes"/>,
failing to supply a parameter value at run-time results in a boilerplate

message such as "XTDE0050: No value supplied for required parameter
somevar".
It would be helpful to be able to supply a custom error message such
as "required: somevar=[true|false|unknown]" to save the user the time it
takes
to look through the code to figure out what parameter is expected.
There's no
way to do this in the XSLT spec through 3.0, correct? and no common
extensions
for doing it?
If not, would that be a useful feature for others, or are there reasons
not to
implement something like that as an extension or enhancement?
