    Problem Summary MSF4W.00015 Test failures due to a non-alignment between the reference code and its specification prior to X11R6.4.
    Problem Text
    The reference implementation (i.e. The X11 code provided by TOG) being
    tested is not in line with the standard specification for this X11
    function as defined in the "X Toolkit Intrinsics - C Language
    Interface".
    The assertion being tested is in line with the standard specification
    but the behavior of this function is not in line with the specification.

    Either the X11 reference implementation is at fault, or the
    Specification needs to be aligned with the reference implemenation. It
    is our understanding that X11R6.1 is no longer supported by TOG,
    hence we request this waiver be granted a Permanent Interpretation.

    The assertion for Xt11/XtCallConverter, TP #11 is:

    When the type converter converter has not been registered
    for the application context associated with display, the
    converter has been previously called with the specified
    arguments, and the conversion failed a call to Boolean
    XtCallConverter(display, converter, args, num_args, from,
    to_in_out, cache_ref_return) shall return False immediately.

    The XtCallConverter doc says:

    The XtCallConverter function looks up the specified type converter in the
    application context associated with the display and, if the converter
    was not registered or was registered with cache type XtCacheAll or
    XtCacheByDisplay looks in the conversion cache to see if this
    conversion procedure has been called with the specified conversion
    arguments. If so, it checks the success status of the prior call, and
    if the conversion failed, XtCallConverter returns False immediately;

    [The implication is that if the previous converstion failed, the
    converter will NOT be called before XtCallConverter returns.]

    If a converter is not registered (via Xt[App]SetTypeConverter), the code

    in Xt (lib/Xt/Convert.c) has two problems that cause TP #11 to fail:

    1. It does not cache the return status from converter functions

    2. It calls the converter regardless of the previous return value for
    the converter

    TP's 12 and 13 fail for similar reasons: no converter is registered
    and on subsequent calls to XtCallConverter, since there is no converter
    cache, the converter is invoked instead of using the values that should
    have been put in the cache during previous calls to XtCallConverter.
    In these two TPs, the to_in_out->size fields contain incorrect values.

    Also, for TP #13, XtCallConverter returns True but is should return
    False.
