I think I understand some of the structure but still the workflow is not
entirely reliable.

I now understand the purpose of this macro and added it to my LaTeX
file.

I also added to catchfilebetweentags.el the macro

;; New macro to provide basic RefTeX support for inserting the label.
    '("ExecuteExternalMetaData"
      (TeX-arg-input-file  "File-name" t) "Tag")

Indeed that works in the current Emacs session.

However,  even after putting these lines in
my reftex_init.el file and byte-compiling it, after a restart of Emacs,  the 
reftex
did not add the correct reference/label to ExecuteExternalMetaData!

I had explicitly to eval these lines again, to make it work. I am sort
of puzzled.
