I needed a way to get an empty attribute in to the current document.
Policy seems pretty much designed to prevent this from happening. So,
working around it:

<rule>
<description>Handle Missing Middle Initials</description>
<conditions>
<and>
<if-op-attr name="Initials" op="not-available"/>
</and>
</conditions>
<actions>
<do-add-dest-attr-value name="Initials">
<arg-value>
<token-local-variable name="Null"/>
</arg-value>
</do-add-dest-attr-value>
</actions>
</rule>
