[oXygen-user] document validation

[George Bina]

Hi Roderik,

This type of problem appears when the content model for an element 
contains twice the same element particle in different places, with 
optional content between these references, something lile
   ...
   <element ref="emphasis">
   <element ref="someOtherElement" minOccurs="0"/>
   <element ref="emphasis">
   ...

In this case when the parser will encounter an emphasis element it will 
not be able to know if it should match that against the first occurrence 
or against the second occurrence of the emphasis element. The XML Schema 
spec requires that only one particle should match, see
http://www.w3.org/TR/xmlschema-1/#cos-nonambig

If you provide the schema then we will probably be able to point you to 
the exact issue there.

Such problems are resolved by writing the content model in a 
non-ambiguous way - that that is not always easy and sometimes it may be 
impossible or practically impossible.

Best Regards,
George
