Validating uniqueness in a XML file using XSLT

Hi,

I want to XSLT to validate the uniqueness for the name
attribute in an XML file. The result will print out
any elements with the duplicated name attributes.

Basically, XSLT needs to look at all the elements with
name attribute and check the uniqueness for its value.

Is there a good way to do that in XSLT?

Thank for any input/comment.

Here is the sample XML

<M name="a">
  <N></N>
  <M name="b">
    <N>12<N>
    <MM name="c"/>
  </M>
</M>
