Models a named query parameter
NOTE: Unfortunately we need to model named and positional parameters separately still until 6.0
NOTE : Also, notice that this still treats JPA "positional" parameters as named.  This will change in
6.0 as well after we remove support for legacy positional parameters (the JPA model is better there).
