Any tricks?

In the case of a customView columns, the behaviour of forward slash is to link to data in another table. What about in the case of the column name actually containing a "/".

<customView xmlns="http://labkey.org/data/xml/queryCustomView">
    <columns>
        <column name="ParticipantId"></column>
        <column name="col (a/l)"></column>
    </columns>
</customView>
(fwiw - I tried html escaping it.)
I've gone against using this technique and instead just edited the the query xml file to hide out columns. Still, would be interested to know if the above can be achieved.
