If the configuration parameter "namespaces" is set to true, this methods
checks if an entity whose replacement text contains unbound namespace
prefixes is referenced in a location where there are no bindings for
the namespace prefixes and if so raises a LSException with the error-type
"unbound-prefix-in-entity-reference"
