Re: Catching message from xsl:message terminate =yes in function

Hi, Christophe

"Note that Saxon inserts a processing instruction into the xsl:message document containing the error code and the location of the xsl:message instruction. This is convenient, but not strictly according to spec.", per https://saxonica.plan.io/issues/4376#note-2

Sorry AirQuick, but why do you expect a value element containing a PI ? 
I can not see in specs a PI being written to outpout...

Best,
Christophe
