Hello,
i notice that the -m option is no longer supported from 11 version but in the documentation the messageEmitter attribute in configuration file seems to be supported but not working ? perhaps a mistake in the documentation.
Thanks

Thank you. I have updated the documentation. All the interfaces to get and set a MessageEmitter are still there, for backwards compatibility, but in 11.x they are ignored.
(For reference, the problem with the MessageEmitter API was that there was no way of making it thread-safe.)
Thank-you for your prompt response.
For my part, I do a lot of pxslt rocessing in multithreading mode by putting a class that translates the xsl: message into log4j and it works very well. Maybe you are referring to multithreading within the same xslt (saxon:treads, allowMultiThreading ...) ?
Correct, Saxon can do multithreading within a single transformation (e.g. if you do xsl:result-document in Saxon-EE). The MessageEmitter interface involved making multiple calls to the same MessageEmitter for a single xsl:message instruction, and if two xsl:message instructions were executed in different threads there was no way the MessageEmitter could disentangle them.
We replaced the MessageEmitter quite a while ago with the MessageListener interface which made a single call to the supplied callback. But we've since revised that to capture all information about a message in a Message object, because we found it was difficult to extend the interface to supply additional information such as the location of the xsl:message instruction.
