Mapping IDL Data Types to an XML Schema (XSD)

In the table below, the following metasymbols and informal terms are used for the IDL.

  • The metasymbols "[" and "]" enclose optional lexical entities.

  • The informal term number (or in some cases number1.number2) is a sequence of numeric characters, for example 123.
