<to variable="tempVar"/>
</copy>
Example 2:
Removes the (N - 1) attachment; that is, removes the second-to-last attachment from the resultMessage variable, where N is the count of attachments on resultMessage.The return value of removeAttachment is copied to the unused tempVar.
<copy>
<from>abx:removeAttachment("resultMessage",
abx:getAttachmentCount("resultMessage") - 1 )
</from>
<to variable="tempVar"/>
</copy>
Example 3:
