Does anyone know of an XML editor that allows valid values to be
obtained from an external document?
I **assume** that the validating editors use valid values that are
explicitly included in the DTD. But, what if the valid values are
huge, for example the country codes or geoloc codes? It'd be nice to
be able to refer (from the DTD) to a document (perhaps an XML doc)
that contains the valid values so that an XML Editor++ would be able
to retrieve the valid values and populate a list or combo box to
assist the user to **select** an appropriate value, rather than making
them enter it from scratch.
Does such an editor exist, is someone building such an editor, or does
the spec allow for this to occur so that it will be done in a
consistent manner across multiple implementations?
