namespaces declared reduntantly

[sydb]

Note: this is similar to, but not the same as, #118, I think.

In those cases where an example has a root element of <TEI> and descendant <TEI>s (i.e. //teix:egXML/teix:TEI//teix:TEI), those descendant <TEI> also (inappropriately) get decorated with an @xmlns namespace declaration in the HTML output. Note that this does not happen if the root element is <teiCorpus>.

(BTW, at the moment this never happens in the released or dev branch Guidelines, only in the sydb-standOff branch.)
