And of course you can use Relax NG (http://relaxng.org/) validation, which
combines power of w3c Schema, and quite readable syntax (esp. with the compact
notation).
While w3c schema has its uses (mostly for data binding), its not all that good
for validation. RNG on the other hand is specifically designed for validation,
and is very good at that.
There both stand-alone RNG validators (Multi-schema Validator, yang) and many
xml parsers natively support validation (not sure about Xerces, but Woodstox
uses msv to implement full parser and writer-side RNG validation; and I think
you can plug-in generic sax validator with Xerces). Also, I think Saxon xslt
/xquery processor can probably do RNG validation as well.

Hhmm I don't know of anything in a DTD that will allow that. Seems like
a java method is the way to go.
Or XML Schema which is a more modern and much more powerful validation
mechanism. Unfortunately, more difficult to learn and a bit rough in syntax. In
schema you can use the uniqueness key to ensure uniqueness of name element
values.
For an example of validation using schema, see here: http://cafeconleche.org

Subject: [jdom-interest] No duplicates element's values in a list of
element
Hi!
let's suppose that we have this xml:
...
<name>name1</name>
<name>name2</name>
...
<name>nameN</name>
Is there a ddt rule that forces to don't have duplicate value of name?
or: i must write a function (using jdom) that recovers all the elements
and controls if there is a duplicate value?
