    Instance.

    for any Properties missing from this list.  Note that if
    <TT>LocalOnly</TT> is specified as <TT>true</TT> (or
    <TT>DeepInheritance</TT> is specified as <TT>false</TT>) this acts as an
    additional filter on the set of Properties returned (for example,
    if CIMProperty <TT>A</TT> is included in the
    <TT>PropertyList</TT> but <TT>LocalOnly</TT> is set to true and
    <TT>A</TT> is not local to a returned Instance, then it will not be
    included in that Instance). If the <TT>PropertyList</TT> input parameter
    is an empty array this signifies that no Properties are included in each
    returned Instance. If the <TT>PropertyList</TT> input parameter is
    NULL this specifies that all Properties (subject to the conditions
    expressed by the other parameters) are included in each returned
    Instance.

    If the <TT>propertyList</TT> contains duplicate elements,
    the Server MUST ignore the duplicates but otherwise process the request
    normally.  If the <TT>PropertyList</TT> contains elements which are
    invalid CIMProperty names for any target Instance, the Server MUST
    ignore such entries but otherwise process the request normally.

    @param filterQueryLanguage If the <tt>filterQueryLanguage</tt>*
    paramter is provided it defines a query language to be used
    with the filterQuery. This is an optional parameter and using it may cause
    the operation to be rejected by some CIM servers.

    @param filterQuery String defining a filter query to be applied to
    the enumeration. This is an optional parameter and using it may cause
    the operation to be rejected by some CIM Servers.

    @param operationTimeout Uint32Arg parameter that defines the
    interoperation timeout in seconds between the response and
    subsequent request operations of an enumeration sequence. The
    server shall maintain a returned enumeration context for at
    least the time specified by this parameter.  If the parameter is
    set to NULL the server defines the operationTimeout time.  If
    the user sets the parameter to a time greater than that allowed
    by the server, the server may use its maximum timeout time in
    place of the supplied parameter or refuse the request with an
    exception. If the client sets the timeout time to zero the
    server may either ignore timeout time completely or refuse the
    request with an exception.

    @param continueOnError Boolean parameter that defines whether the server
    should continue to return instances subsequent to a CIMException error
    occurring in the server.  If this parameter is "true" the server may
    continue processing responses subsequent to an error.  If it is "false"
    the server must terminate the response upon the first error.  This
    parameter is optional and not all servers accept it.  A server may
    generate an exception response if this parameter is set "true'.

    @param maxObjectCount Uint32 parameter that defines the maximum number
    of elements that this Open operation can return. Any Uint32 value is legal
    including 0.
    The server may deliver up to maxObjectCount objects.  The server may
    deliver fewer elements including possibly zero elements. In any case, the
    server will reset the <TT>operationTimeout</TT> when the
    response is generated so that <TT>maxObjectCount</TT> of zero
    can be used to keep an enumeration sequence open without
    receiving elements. This is an optional argument with default =
    0.
