Subject: [PATCH] util: virxml: introduce virXMLFormatElementDirect
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This can be used to format XML where the element has direct value
instead of any subelement. For example:

    <maxMemory slots='16' unit='KiB'>1524288</maxMemory>
