The <li> element has a namespace node for the jtt namespace - that is, the
jtt namespace is in scope for this element. Same applies to its <br> child.
But there's no need for a namespace declaration, because the namespace
declaration is already present on an ancestor element.

If you declare a namespace in the stylesheet because it's used in the source
document, and you don't want the namespace in the result document, then it
always makes sense to mention it in exclude-result-prefixes.

One thing to remember, however, is that the only effect of
exclude-result-prefixes is on literal result elements. If you copy elements
from the source document to the result document using xsl:copy-of, then all
their namespace nodes will be copied too, regardless of e-r-p.
