Hi! Maybe am I missing something but:

some RE data items are defined like in cat004, cat010, cat011...
RE data items are NOT defined in cat019, cat048, cat065.

Example for file asterix_cat048_1_21.xml: RE field is present in but is not defined in a https://github.com/CroatiaControlLtd/asterix/blob/3f765d387d239ccc44e278a2ffa600fb6a6587f9/asterix/config/asterix_cat048_1_21.xml#L1237

Is it a problem or not? Bye ;)

You are right. In some categories RE field is not presents. Reasons could be that there were no specifications for these data available or simply nobody needed them until now :-). Parser will just skip them in such case.
You are free to implement those specifications and I can include them in repository if you like.
