Michael,
Thanks for your quick response.
I will use a simple internal parser to detect them. If the xml is
wellformed this should not be too complex
Thanks,

Even if Xerces internally tracked entity boundaries within attribute
values there would be no way to report this information to you
through SAX [1]. Only the normalized value [2] of an attribute is
exposed. In other words, the entity references will have been
replaced before your ContentHandler receives the attribute values.
