I have 2 messages. One described by a COBOL copy book and one described by a XML Schema. I have created a message set MYMSG.mset with two message defintion files COBOL_MSG.msxd and XML_MSG.msxd. Each has the message COBOL_MSG and XML_MSG inside it.
I now need to model a new message (New_MSG) which is almost the two messages (COBOL_MSG and XML_MSG) appeneded together (only one or two fields from each one not being used). When I use the option create message definition file from COBOL or Schema, a new message defintion file is always created. All I need is just a new message making up of Types from the original two msxd.
If I have all the Types inside one of the existing msxd, I can create the new message from the types
But I cann ot find a way to copy the types from one msxd to another. Is that the right way to do this ? If not what should be the right way ?

The info center talks about "Linking from one message definition file to another" http://127.0.0.1:53644/help/index.jsp. But it does not say what I can expect after that. I did the include because my XML_MSG.msxd has name space and COBOL_MSG.msxd has no name space. I am using XML_MSG.msxd as my target (i.e. specify the include in XML_MSG.msxd).

I then try to create elements for my NEW_MSG. I expect that I can specify types from COBOL_MSG.msxd as the type for the new local element. But I cannot get it listed under the Type drop down.

Is this how it is suppose to work ?

The important thing to remember is this: a message set is just a collection of xsd files that happen to have the extension '.mxsd'. Message definition files are linked together in the same way as any other xsd - using xs:import and xs:include directives. So your second post is on exactly the right lines - you need to import or include the (m)xsds that contain the library types.

No idea why you are not seeing the included types listed in the Type dropdown. I assume that they are *global* types in the included xsd ( because if not, that would explain your problem).

btw, when you include ( rather than import ) a no-target-namespace xsd into a namespaced xsd, you will get the 'chameleon' effect. The global definitions in the included xsd will take on the namespace of the host xsd. You probably found that out already.
