/**
 * 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).
