I think I know why he wants them. Tomas has made it possible to dissect NonStandardParameter stuff (NonStandardIdentifier/h221NonStandard respectivelly NonStandardIdentifier/object) from a plugin.

A plugin can then register e.g. as:
dissector_add("h245.nsp.h221", 0xb500534c, netmeeting_h221nonstd_handle);
or 
dissector_add("h245.nsp.object",ADLER_MYOWN_NONSTD_OBJ,myown_nonstd_handle);

Then it might be useful to use e.g. dissect_h225_TransportAddress from the plugin.

Actually I started to make some experiments with making a plugin for certain h221NonStandard data yesterday and what I remember the ASN.1 specification for that specific data was using both TransportAddress and NonStandardParameter (i.e. including
another NonStandardParameter in the h221NonStandard data) so I probably want to use them also - when I have time to continue with my experiments.
