Identifiers
Any text not contained in quotes and adhering to the following rules is an identifier that refers to data in the context in which the expression is evaluated.
An identifier:
Includes one or more letters (a-z or A-Z), digits (0-9) or underscores
Starts with at least one letter
For the programmers, the following snippets are from the official grammar:
ID : LETTER (LETTER|DIGIT|'_')*;
fragment DIGIT : '0'..'9';
fragment LETTER : ('a'..'z'|'A'..'Z');
Chaining
Identifiers can be chained together using dots (".") to reference functions or identifiers in nested namespaces.
For example:
Trim(LastName)Trim(Company.Address.City)CreateGuid(Company.Address.City)
