Example
<p>The <gi>xhtml:li</gi> element is roughly analogous to the <gi>item</gi> element, as is the
<gi scheme="DBK">listItem</gi> element.</p>

This example shows the use of both a namespace prefix and the schema attribute as alternative ways of indicating that the gi in question is not a TEI element name: in practice only one method should be adopted.
