If enabled, the parser will understand and parse variable definitions
contained in a fragment definition. They’ll be represented in the
variableDefinitions field of the FragmentDefinitionNode.
The syntax is identical to normal, query-defined variables. For example:
fragmentA($var:Boolean=false)onT{ ... }
optionalnoLocation
noLocation?: boolean
By default, the parser creates AST nodes that know the location
in the source that they correspond to. This configuration flag
disables that behavior for performance or testing.
