[xsl] user error

[Mike Sokolov <sokolov@xxxxxxxxxxxx>]

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.
