I assume you want to use a sort of \label/\ref-mechanism for this,
right?  If true, you have to go through some hassle to teach RefTeX
about this.  First, you would usually add \ExecuteMetaData to
`reftex-include-file-commands', but the variable looks for a mandatory
file argument, not optional.  So you have to define a new LaTeX macro
for this:

  \newcommand{\ExecuteExternalMetaData}[2]{%
    \ExecuteMetaData[#1]{#2}%
  }

Then you need to add <*TAG-NAME> to `reftex-label-regexps'.  Finally,
you need to write a little lisp for your `ExecuteExternalMetaData' which
asks for two arguments, file name and then runs `reftex-label' with the
`no-insert' argument set to t in order to get only the label and insert
that without \ref.  This is the first part I tried and it works in terms
of RefTeX sees the labels in an external file (note that they are
commented out, you need to hit '%' to make them visible in RefTeX Select
buffer)

  (add-to-list 'reftex-include-file-commands
               "ExecuteExternalMetaData" t)

  (add-to-list 'reftex-label-regexps
               "<\\*\\(?1:[^>]+\\)>" t)

  (reftex-compile-variables)
