Attribute Types

Catalogue of the schemas/types/grammars expected by attributes.

The following list gives the legal strings corresponding to values of the given types. The syntax for describing legal type strings is a mixture of literal strings, stdio encodings (e.g., %f for a double), and regular expressions. For regular expressions, (...)* indicates 0 or more copies of the expression enclosed in the parentheses, (...)+ indicates 1 or more, and (...)? denotes 0 or 1 copy.
