B.1 Notational Conventions

The syntax definitions follow the Enhanced Backus Naur Form (EBNF) [114] with the following exceptions:

• The $\sim$ symbol is used to denote a sequence of characters. E.g. "$\sim$ a" means the whole character set except for the character a.

• Semantical predicates are denoted by a Sans Serif type setting and the syntax described in the ANTLR users manual (e.g.: "{dim == 1}?").

• Teletype typing denotes terminal symbols (e.g.: "POINTS" or "ATTRIBUTES").

• Italics type setting denotes non-terminals (e.g.: "ident" or "string").
