The most common uses I have seen for entities are: 1. to create macros for commonly used content-model groups; and 2. to create a kludge for working around the lack of support for namespaces in DTDs. The first is handled fairly well by named groups (<xsd:group name=...) and the second problem doesn't exist because XML Schema supports namespaces. External entities in DTDs correspond pretty well to the <xsd:include ...> element in XML Schema. Perhaps someone who *really* knows what they're talking about (Henry?) can elaborate or correct any misinformation I've dropped here. :->} -- Bob Kline mailto:bkline@r... http://www.rksystems.com
