  • Summary:

    2. 69.8.2.8 The simple Element, page 69-538
    Simple Extensions and Changes
    a) Enumerations - Add an optional enumerations element to the simple
    definition.
    This allows a simple enumeration property to be defined. Each enumeration
    label
    has an associated value. The values are all of the same simple type.

    Change simple element to:

    <!ELEMENT simple
    ( description?
    , value
    , choices?
    , enumerations?
    , defaultvalue?
    ) >

    Define new enumerations element

    <!ELEMENT enumerations
    ( enumeration+
    )>
    <!ELEMENT enumeration EMPTY>
    <!ATTLIST enumeration
    label CDATA #REQUIRED
    value CDATA #IMPLIED>

    b) Short appears twice in the simple type attribute definition. Remove
    second
    occurrence.
    <!ELEMENT simple
    ( description?
    , value
    , choices?
    , defaultvalue?
    ) >
    <!ATTLIST simple
    name CDATA #IMPLIED
    type ( boolean

    char
    double
    float
    short – 1st occurrence
    long
    objref
    octet
    short – 2nd occurrence
    string
    ulong
    ushort
    ) #REQUIRED >

    c) Units - add an optional units element to indicate the units of
    measurement for
    a simple property.

    <!ELEMENT simple
    ( description?
    , value
    , choices?
    , units?
    , defaultvalue?
    ) >

    <!ELEMENT units (#PCDATA)>

    d) Property Kind - The properties file for a component should not be
    restricted to
    only initial configuration properties. A component has many different types
    of
    properties and when defining a component one should be able to define these
    types of properties in a generic way. Add a kind element or attribute for a
    property definition. A component has readonly, writeonly, and readwrite
    properties. Simple properties can also be used for a component factory's
    create
    options parameter (home) or executable parameters/arguments. Only simple
    properties can be used for executable parameters.

    New simplekind element

    <!ELEMENT simplekind EMPTY>
    <!ATTLIST simplekind
    kindtype (configure_writeonly | configure_readwrite | execparam |
    query_readonly | factoryparam) "configure_readwrite">

    Change simple definition to:

    <!ELEMENT simple
    ( description?
    , value
    , choices?
    , simplekind*
    , defaultvalue?
    ) >

    The propertykind can be an optional element or attribute for the stuct and
    sequence elements.

    New propertykind element

    <!ELEMENT propertykind EMPTY>
    <!ATTLIST propertykind
    kindtype (configure_writeonly | configure_readwrite |
    query_readonly | factoryparam) "configure">

    Change Struct and Sequence to

    <!ELEMENT struct
    ( description?
    , ( simple

    sequence
    struct
    valuetype
    )*
    , propertykind?
    ) >
    <!ATTLIST struct
    name CDATA #IMPLIED
    type CDATA #REQUIRED >

    <!ELEMENT sequence
    ( description?
    , ( simple*

    struct*
    sequence*
    valuetype*
    )
    , propertykind?
    ) >
    <!ATTLIST sequence
    name CDATA #IMPLIED
    type CDATA #REQUIRED >
