xml-dev - Re: Array content model

["Anders W. Tell" <anderst@toolsmiths.se>]

One way of looking at it is through OO lenses. In most OO languags and practices

collections are a first class consideration, even in UML multiplicity is
modelled.
Since an XML stream is only an encoding of something and if this something is
based on a
OO model then collections may, IMO should, be explicitly represented in the XML
stream.

There are at least three ways to encode an array *stereotype*:

1.
<items kind="C++ templates,STL">
  </item>
</items>

2.
<array kind="generic collection">
  </item>
</array>

3.
<array kind="generic array with realationship info">
  <array-member name="local name">
    </item>
  </array-member>
</array>

The difference between 2. and 3. encoding *forms* is that in 3. relationship
related information may be encoded in the <array-member> element.
This means that all contained elements DTD or schema does not need to be changed

depending on its container and the relationship between them.
