class Directory from TDataStd inherits Attribute from TDF

    	---Purpose: Associates a directory in the data framework with
    	-- a TDataStd_TagSource attribute.
    	-- You can create a new directory label and add
    	-- sub-directory or object labels to it,


uses Attribute       from TDF,

    	-- If a directory attribute is found, true is returned,
    	-- and the attribute found is set as D.

    returns Directory from TDataStd;

    	---Purpose:  Creates a new sub-label and sets the
    	-- sub-directory dir on that label.

    MakeObjectLabel (myclass; dir : Directory from TDataStd)
    	---Purpose:  Makes new label and returns it to insert
