Overview
As it is the case for intrinsic functions, condition functions have a full function name, and a short form. For more details see:
Fn::If: !If
Fn::And: !And
Fn::Equals: !Equals
!Equals ['something', !Ref SomethingElse]
Fn::Not: !Not
Fn::Or: !Or
Expressions
Expressions can use pseudo-parameters, template input parameters and mappings. Expressions are useful when declaring Conditions. Other conditions can be referenced within conditions.
