---------------------------------------
Moving out, no way this is in scope for 3.2.
> xsd sequence validation reporting errors too late

> Key: XERCESC-1881
> URL: https://issues.apache.org/jira/browse/XERCESC-1881
> Project: Xerces-C++
> Issue Type: Bug
> Components: Validating Parser (XML Schema)
> Affects Versions: 3.0.0, 3.0.1, 3.1.0, 3.1.1, 3.1.2, 3.2.0, 3.1.3, 3.1.4
> Environment: Windows Visaa 32, Xerces 3.0.1
> Reporter: Brian Hoyt
> Fix For: 4.0.0
>
>
> Validation using the following xsd and xml results in two different results
> between XercesJ and XercesC++.
> For java I get the error reporting the sequence error right after the
> processing of element <url> because <name>
> cannot appear after <url>. But for C++ the error is not reported until the
> last element within <person> has been
> processed. This obviously isn't correct because by that time it is too late.
> The way Java is reporting it seems to
> be correct so that I can stop processing the xml file.
