An aside about terminology
n SGML and XML 1.0 talk about element types
n XML Schema to date has been more casual and
just talked about elements
ä Meaning either an element in an instance
ä Or the abstraction which is described in a DTD or
Schema
n Further confused by XML Schema making
extensive use of type
n Also, schema means many different things to
different people
ä I'll try always to say/write XML Schema. . .
