AutoGen handles definitions in XML form by converting XML format to AutoGen Definition format. There is a small amount of information loss, as follows:

White space is stripped.
Leading and trailing white space is stripped. If there is nothing but white space, no text entry is made.

DTD's are not required
Whatever is present in the XML text will show up in the definitions.

template selection
If the top level entity has an attribute named ``template'', then you can omit the ``-T <template-name>'' option to xml2ag.

attributes
Attributes are assigned plain text values

entities
Entities always have structured values.

ordering
Ordering between differently named siblings is lost. All siblings of the same name (e.g. the two "grumbles") have ordered preserved. However, there is no ordering between the grumbles and texts within the mumbling below.

Here is a simple example of XML text:
   
<?xml version="1.0"?>
<ag_example template="sample.tpl">
  <mumble attr="foo">
    <grumble>
      &lt;stumble around the 'XML'.&gt;
    </grumble>
    mumble-1
    <!-- This is just a
         /* multi-line comment */ -->
    mumble-2
    <grumble>
      grumble &amp; "grumble" &amp; grumble.
    </grumble>
    mumble, mumble
  </mumble>
  <stumble upon="rough going"/>
</ag_example>
and the resulting output, derived by filtering the above text through: ``xml2ag -O-''
