params[] constraint definition?

Greetings!

I havn't read ISO/IEC 14496-1 (is this publically available?) could someone
please help me out with the following:

I am wondering whether there is a normative method for specifying
constraints (valid range/usage) of fields in the params[] array?

For example, I'd like to be able to write a parameter specification along
the lines of this (XML for clarity):

<bifs-audiofx-params-spec>
    <param index=0>
        <name>Base Frequency</name>
        <range><min>0.</min><max>22000</max></range>
        <unit>Hz</unit>
    </param>
    <param index=4>
        <name>Feedback Amount</name>
        <range><min>0.</min><max>1.</max></range>
        <unit>None</unit>
    </param>
</bifs-audiofx-params-spec>

If anyone knows of any existent work in this area could you please let me
know.

Best wishes,

Ross.
