    This XSLT stylesheet transforms ChangeLogML content into a XHTML
    fragment whose top-level element is a "span". The content of the
    element is the version-string (from the @version attribute) of the
    newest release, as sorted by the @date attributes.

    The template recognizes only the following input parameter:

    class
      Allows the user to specify a CSS class for the span. If not given,
      the class defaults to "changelog-version-span".

    This snippet contains most of the core XHTML-generation templates. It will
    also be used by the stylesheets that generate only div's, ul's, etc.
    Some will use xsl:import rather than xsl:include so as to override some
    functionality, but for this stylesheet everything is needed as-is.

  <!--
    This snippet-file contains common variable declarations (date at the moment,
    the "credits" string to identify the processor) and non-content templates
    such as the date-formatter (which only returns a string, no XHTML or
    plain-text-specific material).

  <!--
    The "class" parameter controls the CSS class assigned to the outer-most
    containing div element. The rest of the content uses the same set of
    classes as the other XHTML-oriented styles do. But specifying this should
    allow the user to set up their own complete hierarchy, using the right
    selectors.
