	/// validation, analogue to a compiler.  This allows a process developer to 
	/// correct more then one problem before redeploying the process archive.  
	/// Each message is optionally composed of a list of sub-messages separated 
	/// by colons ':'. The sub-messages are ordered from general to specific.
