RE: [xsl] error in xsl:key

It's a dynamic error like any other, and all dynamic errors are fatal.

The system has a lot of discretion in exactly how evaluation proceeds. For
example, if evaluating a global variable throws an error, but you never use
the variable, then it's processor-dependent whether your stylesheet will
fail or not. The same is true to an extent here - except that key() really
can't return a result until the use expression has been evaluated for every
node that matches the xsl:key/@match pattern.
