Help creating DTD

["Karl Stubsjoen" <karl@excelbus.com>]

Hello,

I need help creating a DTD.  Actually, is it a DTD that I mean to create?  I
have an existing XML document, from this I need to create a *template*
(dtd?) which I can then use to validate future XML documents.

My XML document looks like this:

  <?xml version="1.0" encoding="UTF-8" ?>
- <ORDER>
  	<UID>DSM/RSM USER NAME</UID>
  	<DEALER>21</DEALER>
- <ORDERS>
  	<ITEM id="0116602800">7</ITEM>
  	<ITEM id="1106500706">8</ITEM>
  	<ITEM id="1106502706">9</ITEM>
  	<ITEM id="1106700706">5</ITEM>
  	<ITEM id="1106702706">7</ITEM>
  	<ITEM id="0100102883">3</ITEM>
  	<ITEM id="0100100805">333</ITEM>
  	<ITEM id="0101000725">5</ITEM>
  </ORDERS>
  </ORDER>

I'll try and describe the above:

<ORDER> can contain any number of child elements
<UID> must be included
<DEALER> must be included
<ORDERS> must be included

<ORDERS> can contain multiple ITEM(s) but restricted to just ITEM nodes
<ITEM> must have unique id property and the value of item must be numeric >
0

Thanks for the help!
*meanwhile I will give this a go myself!*
