The structure of XoomXML

Working upwards:

• Parameters are the individual settings that collectively make up configuration.
• Items are smallest addressable units of configuration, and therefore have a unique, environment-independent Xoom identity. Items exist at the third level of XoomXML (see diagram below). Technically items can contain zero parameters but typically contain more.
• Items are assigned to a type. Types exist at the second level of XoomXML.
• The document element, or root, is required by XML. In XoomXML it can have any name.

<Root><!-- Can be called anything -->
  <Type><!-- Items are assigned to a type, for example Region -->
    <Item xoom:id="Type[Name]"><!-- Items are assigned an environment-independent ID -->
      <ParameterA>Value</ParameterA><!-- Items contain parameters -->
      <ParameterB>Value</ParameterB>
      …
    </Item>
    …
  <Type>
    <Item xoom:id="Type[Owner|Category|Subcategory|Name">
      <ParameterC>Value</ParameterC>
      …
    </Item>
    …
  </Type>
  …
</Root>
