ParseDeclaredVariableValues processes a map of unparsed variable values and returns an input values map of the ones declared in the specified variable declaration mapping.

ParseUndeclaredVariableValues processes a map of unparsed variable values and returns an input values map of the ones not declared in the specified declaration map along with detailed diagnostics about values of undeclared variables being present, depending on the source of these values.

ParseVariableValues processes a map of unparsed variable values by correlating each one with the given variable declarations which should be from a root module.
