Size constraints for H225_ArrayOf_EnumeratedParameter

I have encountered something which looks like a bug. When I add parameters to my custom H460_Feature via
H460_FeatureTable table;

table.AddParameter(id, content);


H323Plus produces malformed packet with incorrectly encoded size of H225_ArrayOf_EnumeratedParameter. I’ve found that size constraints for H225_ArrayOf_EnumeratedParameter are not beeing set, however, according to spec, they had to be set. So, if my conclusion is right, I propose a small patch like the following:

--- h225_2.cxx.orig 2013-07-23 00:26:59.000000000 +0600
+++ h225_2.cxx 2017-10-23 11:00:27.000000000 +0500
@@ -19,6 +19,7 @@
H225_ArrayOf_EnumeratedParameter::H225_ArrayOf_EnumeratedParameter(unsigned tag, PASN_Object::TagClass tagClass)
: PASN_Array(tag, tagClass)
+ SetConstraintBounds(PASN_Object::FixedConstraint, 1, 512);
