    Hi, Paul:

    Yes, that's my understanding of the dual role of navtitle - to cache the topic title inline so the map provides an intelligible outline and (as an extra option) permit overriding the topic title to provide a contextual title in a navigation.

    [dita] Navtitle and locktitle

    It's a bit subtle, but I read the DITA spec as saying that the navtitle
    attribute is totally meaningless (ignored) from a publishing point of
    view unless the locktitle attribute is set. As a performance
    enhancement, I would like XMetaL DITA Edition to "cache" the navtitle
    from titles in documents similar to the way it caches the content of
    conrefed content. This allows us to load a document without downloading
    every referenced document from the CMS to look at its title.

    This means that if we load a document with "navtitle='foo'" and
    "locktitle='no'" then we will feel free to overwrite the navtitle based
    on the content of the referenced document. Alternately, if the locktitle
    = 'yes' then we will presume that the navtitle is real and important and
    therefore leave it alone.

    Does this seem correct to DITA's designers? The alternative is to cache
    the title in a processing instruction which will just introduce extra
    junk into the DITA document.
