CORBA34 — 69.8.2.9 The sequence Element

  • Key: CORBA34-107
  • Legacy Issue Number: 5511
  • Status: closed  
  • Source: Raytheon ( Jerry Bickle)
  • Summary:

    Simple Sequence -The current definitions for sequence allow invalid
    definitions to be
    built but be syntactically correct. A better definition for a simple
    sequence would be as
    follows:

    Current sequence element

    <!ELEMENT sequence
    ( description?
    , ( simple*

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

    Change to

    Add a new simplesequence element:

    <!ELEMENT simplesequence
    ( description?,
    , values?
    , choices?
    , range?
    , enumerations?
    , units?
    )>
    <!ATTLIST simplesequence
    name CDATA #IMPLIED
    type ( boolean | char | double | float | short | long | objref |
    octet | string | ulong

    ushort ) #REQUIRED

    <!ELEMENT values
    ( value+
    )>

    Change sequence to:

    <!ELEMENT sequence
    ( description?
    , ( simplesequence

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

    One does not have to keep repeating the same simple definition. This
    definition
    then has the added advantage where simple name attribute can now be made
    mandatory.
    <!ELEMENT simple
    ( description?
    , value
    , choices?
    , defaultvalue?
    ) >
    <!ATTLIST simple
    name CDATA #REQUIRED
    type ( boolean

    char
    double
    float
    short
    long
    objref
    octet
    string
    ulong
    ushort
    ) #REQUIRED >
