The default value for @locktitle is "no". To quote from its
    description in
    http://docs.oasis-open.org/dita/v1.2/cd03/spec/common/topicref-atts.html
    :

This attribute makes sure the navtitle element or attribute is used
    if it is present.
    If locktitle isn't set
    to "yes", the navtitle is ignored and text
    is retrieved from the
    target.

I.e. if you want to use a navtitle you have to explicitly set
    locktitle to "yes" - hence its default, implied value must be "no".
