CMake Documentation Guideline

Currently reading the CMake Documentation, I am wondering if there is any agreed on syntax guideline for it.
For example from the Command Invocations part:

command_invocation ::= space* identifier space* '(' arguments ')'
identifier ::= < match '[ A-Za-z_ ][ A-Za-z0-9_ ] * ' >

I can roughly deduce the meaning. Anyway it would be nice to have some common guidelines ( e.g. why ::= , is [...]* a UNIX Regular Expression as well as space*, ...)

It's using BNF (Backus-Naur form), which is a de-facto standard for specifying programming language grammars.
