RE: [xsl] [XSLT 2] rescue

["Michael Kay" <mhk@xxxxxxxxx>]

Unfortunately there is no try-catch in XPath 2 or XSLT 2.

We debated putting one in, but people felt it was a bridge too far.
People were particularly concerned about defining exactly what state the
system was in if an error was trapped and ignored, for example, should
it effectively be required to do a "rollback" of the result tree.
