In the OSF/Motif Programmer's Reference, page 1-477, it says

	"One additional WorkArea child may be added to the FileSelectionBox
	after creation."

I would like to add just such a WorkArea child, but in the XmFileSelectionBox
Resource Set I can not find anything like an XmNworkArea resource.

What I can find is the XmFileSelectionBoxGetChild function to which you
can set the child parameter to XmDIALOG_WORK_AREA, however, there is no
corresponding XmFileSelectionBoxSetChild.

In the OSF/Motif Programmer's Guide, page B-10, it states that the
XmFileSelectionBox can "Controls" an XmWorkArea. I have tried adding
an XmWorkArea in the Controls list of an XmFileSelectionDialog that was
created via UIL. I can compile this UIL file with errors or warnings, etc.
But when I Fetch the XmFileSelectionDialog widget I get 

	Warning: Urm__WCI_LookupClassDescriptor: Couldn't find class
	 descriptor for class XmCreateWorkArea - MrmNOT_FOUND

and I suspect that this may be because there is no such XmWorkArea widget,
but also note that on page B-39 there is an XmWorkArea object, but as far
as I know there is no such object in the Motif Toolkit.

	My specific need is for a third list in the XmFileSelectionBox
widget. I don't even know if this can be done.

	Anybody got any clues, answers, insights, etc.
