What is a valid XML document?If an XML document specifies the DTD or schema of its document type and data structure and is associated with it, and the validation is correct.
Use DTD to define XML elements

Because the graphical process designer (GPD) functionality provided by JBPM is not particularly comprehensive, many designs cannot be completed entirely in the graphical interface. So, in many cases, we need to directly edit JPDL's XML source code, so,It is a good idea to specify schema for JPDL XML. Benefits:1. Quick call out syntax hints via shortcut key "alt+/
