Text that used dynamic values will need to be rewritten to use the tc:messageParam tag. For example, a message that said:

Share documents to <tc:out value="${cjb.vendorName}" /> in Collaborati.

Becomes:

<tc:message key="custom.VEN$.screen.xml.vendorDocumentSharing.shareDocumentsToVendor">

<tc:messageParam value="${cjb.vendorName}"/>

</tc:message>

...and you create a corresponding custom message with key "custom.VEN$.screen.xml.vendorDocumentSharing.shareDocumentsToVendor" and text "Share documents to {0} in Collaborati."
