XML access control by custom ID

Good day,

I am trying to create and use a separate filter XML file to use with a
source XML file. The filter XML will be a listing of my own ID's and
the rights that the target audience have on these elements. The idea
is this:

data.xml
<a some_attributes="xyz" my_id="1">
   123
</a>
<b attribute="xxx" my_id="2">
   ABC
</b>

access.xml
<administrator>
 <read>
    <1/>
    <2/>
</read>
 <write>
    <1/>
    <2/>
 </write>
</administrator>
<anybody>
 <read>
    <1/>
 </read>
</anybody>

accesscontrol.xsl using anybody as parameter
<the magic xslt that I'm looking for>

result.xml
<a access="read" some_attributes="xyz my_id="1">
   123
</a>

Thanks,
Jacobus
