    This XSLT stylesheet transforms ChangeLogML content into a plain-text
    fragment whose content is just the version-string of the newest release
    (as sorted by the @date attributes). None of the head or tail-end content
    as generated for the full plain-text changelog is included, and the
    content does *not* end with a new-line, in case the resulting output is
    intended for inclusion in a plain-text file where the extra new-line
    might be undesirable.

    The template utilizes no input parameters.

    This snippet contains most of the core text-generation templates. It will
    also be used by the stylesheets that generate only partial content. Some
    may 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).

    This template starts the process, at the root of the ChangeLogML document.
    For this style, we only want the newest of the releases, with none of the
    boilerplate (not even credits).
