Fix language-badge leaking into view heading

A language-tagged dct:title renders (xhtml:DefinitionDescription) as a
<dd> with a leading language-badge <span>, so xsl:value-of over the whole
element prepended the tag to the heading (e.g. "enCurrent members").
Select the value text() node only, dropping the badge; [1] guards against
multiple language values.
