Hi all, One of the most useful extension steps (not only) for debugging XProc pipelines is a "message" step that can be used for displaying (possibly dynamic) messages on the console. At the moment, both Calabash and Calumet have their own proprietary implementations of this step, but I think that adding the "message" step to the EXProc library would be much appreciated by the XProc users. This is how the step is declared in Calumet: <p:declare-step type="x:message" xmlns:x="..."> <p:option name="message" required="true"/> <!-- string --> <p:option name="stderr" select="'true'"/> <!-- true/false --> <p:option name="stdout" select="'false'"/> <!-- true/false --> <p:input port="source" sequence="true"/> <p:output port="result" sequence="true"/> </p:declare-step> The step behaves similar to p:identity, except that it has a required option "message" that specifies the message to be displayed on standard output and/or standard error output (controlled by the "stderr" and "stdout" options). (I believe the "message" step in Calabash behaves similarly.) Regards, Vojtech -- Vojtech Toman Principal Software Engineer EMC Corporation toman_vojtech@emc.com http://developer.emc.com/xmltech
