In several parts of this book, we have included simple grammar specifications for many, but not all, of the language constructs introduced in this book, to provide you with a fast way to understand the grammar of a particular construct and its valid combinations. In this grammar syntax, the XML occurrence operators ( ? , * , and + ) are used to specify more precisely the number of times an element may occur in a particular construct:

x

Indicates x is to be used verbatim ( constant width )

x

Indicates x is supplied by the programmer ( constant width italic )

x?

Indicates x may occur zero or one times.

x*

Indicates x may occur zero or more times, separated by commas.

x+

Indicates x may occur one or more times, separated by commas.

[...]

Indicates a logical grouping of code elements, when not implicitly grouped using the verbatim terms { } , ( ) , and [ ] .

[xy]

Indicates only one of a choice of code elements may occur.
