Description bmf1972 2003-03-26 03:08:53 UTC 
Having the following XML document:
<doc>
  <elm1 alias="SameAlias" />
  <elm2 alias="SameAlias" />
</doc>

and the following XSD (fragment) document:
<element name="doc">
  <unique name="alias">
    <selector xpath="elm1|elm2" />
    <field xpath="@alias" />
  </unique>
</element>

the validation is succesfull...

It appears that the xpath union expression is
ignored and only the first union member (i.e.,
elm1) is utilized.

Actually IDE delegates parsing logic to external parser. The external
parser is located using JAXP API. You can at any time change parser
implementation. Try to plug in latest Xerces2 impl from xml.apache.org.

I can recall that Xerces2 implementation that we bundle by default
intentionaly ignores some contraints set by XMLSchema for performance
reasons
<http://xml.apache.org/xerces2-j/features.html>.

I'm going switch it on and let you know (but it's Xerces specifics).

The schema-full-checking feature does not influence XML document checking.

I duplicated the bug into Apaches' bugzilla
<http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18372>.

Perhaps this got fixed in 5.5 Ent Pack when we introduced a new set of tools to work with schemas.
