XMI12 — XML attribute encoding of values underspecified

  • Key: XMI12-49
  • Legacy Issue Number: 4063
  • Status: open  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    Assuming that XMI 1.2 retains XMI 1.1's optional encoding of DataType
    values as XML attributes, the specification needs to be fixed as follows:

    • It should list that DataTypes that can be encoded in two ways,
      how they are encoded, and the meta-model and runtime contexts under
      which this is legal.
    • The spec should say how a decoder should deal with anomalies like
      the following:

    <some.attr xmi.value="1">1</some.attr>

    <someother.attr xmi.value="1">2</someother.attr>

    <multi.attr xmi.value="1" />
    <multi.attr>2</multi.attr>

    <string.attr xmi.value="hi">
    </string.attr>

    Which (if any) of the above is legal?

    • The spec should state explicitly that a decoder that does not
      look in both the xmi.value attribute and the content is not
      XMI 1.2 conformant. [Not that this helps much in practice :-(]
