A few typos but basically correct:

<input type="dropdown" token="cc" searchWhenChanged="true">
<label>Country</label>
<choice value="AU">AU</choice>
<choice value="AK">AK</choice>
<choice value="UK">UK</choice>
<change>
<condition><unset token="form.inpst"></unset></condition>
</change>
</input>
<input type="multiselect"  token="inpst" searchWhenChanged="true" depends="$cc$">
<label></label>
<fieldForLabel>desc</fieldForLabel>
<fieldForValue>desc</fieldForValue>
<search>
<query>lookupQuery|where cc="$cc$"|fields desc
</query>
</search>
<delimiter> OR </delimiter>
<valuePrefix>InputSource="</valuePreix>
<valueSuffix>"</valueSuffix>
</input>

In the change handler for the "parent" dropdown, unset the form.childdropdown token or set it to an empty value
