Issue 14: Tweaked proposal

[Mike Edwards <mike_edwards@uk.ibm.com>]

Folks,

I'd like to propose a subtle variant
of one of Anish's proposals as the resolution for Issue 14:

Single valued property, simple type:

<property name="currency" value="EURO"/>

and the following is equivalent and allowed, although
relatively verbose....

<property name="currency">
  <value xsi:type="xs:string">EURO</value>
</property>

Multi-valued property, simple type:

<property name="currency">
  <value xsi:type="xs:string">EURO</value>
  <value xsi:type="xs:string">USDollar</value>
</property>

...but xsi:type="xs:string" should be the
default, so that the following
shorter form is correct for a collection of strings:

<property name="currency">
  <value>EURO</value>
  <value>USDollar</value>
</property>

Single valued property, complex type:

<property name="complexFoo">
  <value xsi:type="foo:MyComplexType" attr="bar">
    <foo:a>AValue</foo:a>
    <foo:b>InterestingURI</foo:b>
  </value>
</property>

GED type declaration:

<property name="foo">
  <value>
    <SomeGED ...> ... </SomeGED>
  </value>
</property>

Multi valued property, complex type:

<property name="complexFoo">
  <value xsi:type="foo:MyComplexType" attr="bar">
    <foo:a>AValue</foo:a>
    <foo:b>InterestingURI</foo:b>
  </value>
  <value xsi:type="foo:MyComplexType" attr="zing">
    <foo:a>BValue</foo:a>
    <foo:b>BoringURI</foo:b>
  </value>
</property>

Multi valued property, GED type declaration:

<property name="foo">
  <value>
    <SomeGED ...> ... </SomeGED>
  </value>
  <value>
    <SomeGED ...> ... </SomeGED>
  </value>
</property>


It is a great idea for the <value/> element's
@xsi:type
attribute to have a default value of "xs:string"
so that the attribute
can be left out in the common cases of the properties
being strings.


Yours,  Mike.
