	; DOMI is an extrinsic to insert NHIN ARRAY FORMAT arrays into the DOM
	; it returns 0 or 1 based on success.
	;
	; INARY is passed by name and has the format shown above
	; HANDLE is the document number in the DOM (both MXML and EWD DOMs will
	; be supported eventually - initial implementation is for MXML
	;
	; PARENT is the node id or tag of the parent under which the DOM will
	; be populated. If it is numeric, it is a node. If it is a string, the DOM
	; will be searched to find the tag. If not found and there is no root,
	; it will be inserted as the root. If not found and there is a root, it
	; will be inserted under the root.
	;
	; For the above example the call would be OK=$$DOMI("GNARY",0,"results")
	; because "results" is the root tag. Use OUTXML to render the xml from
	; the DOM.
