Re: [xsl] user error

Thanks! That's exactly what I was looking for. I like the syntax better than the XPath version, although it's also worth noting the differences between the output generated by the two methods. Using Saxon, at least: the XPath error() generates a stack trace, which may be helpful, wheras xslt:message seems to rely on the stylesheet writer to generate whatever contextual info is required.

Is there a recognized idiom for throwing an exception in XSLT that would abort processing and pass the error state (message, at least) to the invoker of the transformation?
It looks to me as if this can be achieved using the XPath error() function, but I'm just wondering how folks would typically invoke that.
Using <xsl:value-of select="error()" /> seems like the most unobtrusive, but I wonder if there is some built-in XSLTism for this.

Review <xsl:message terminate="yes"> for what you need.

I hope this helps.
