Mixing adds, deletes and commit in the same message

[Leonardo Santagada]

I tried to put some adds and deletes in the same request to solr but  
it didn't work, have I done something wrong or this is really not  
suported?

This is one example:
<add>
        <doc>
                <field name="kind">document</field>
                <field name="uid">one9a10b11c12d</field>
                <field name="title">Test Document</field>
        </doc>
</add>
<commit/>


Thanks in advance
