(Optional) If this is not specified, then the package assumes that the first parameter is the name of a package/procedure/function and resolves the name.

Set to 'P' or 'p' to fully specify that the input is the name of a package/procedure/function.

Set to 'T' or 't' to specify that the input is the name of a type.

Set to 'R' or 'r' to specify that the input is the name of a trigger.

Set to 'Q' or 'q' to specify that the input is the name of a sequence.

In case the first argument is a cursor address and hash-value, the parameter should be set to any character except 'P' or 'p' or 'Q' or 'q' or 'R' or 'r' or 'T' or 't'.
