I believe a dangling reference is an SML reference, for which at least one scheme is specified, but which is not retrievable using the retrieval mechanism defined by any scheme the implementation supports. Need to cover several cases: - SML reference (defined elsewhere) with no child content - ...with child content containing no sml schemes - ... ... no sml schemes supported by the impl - ... ... at least one scheme supported by the impl Nb: if SML changes to support schemes via attributes on the sml:ref=true element, more cases become relevant. 15929 1 kumarp 2007-07-26 06:55:22 +0000 The following cases identified by John should be covered under the definition of a null reference. - with child content containing no sml schemes - no sml schemes supported by the impl I have opened the following bug for this. 4884 update the definition of a null reference to include the unimplemented-schemes case
