Jesse Pelton commented on XERCESC-1736:
---------------------------------------
Denis,
When I asked whether you could create a patch, what I meant was whether you
could create a patch file ("unified diff" is the preferred format, I think)
that could be applied to the most recent version of the code to produce the
behavior you think is correct. In short, I was suggesting that you submit code
that fixes the problem as you see it.
Since David has already updated the documentation to agree with the code's
behavior, the behavior is unlikely to change unless someone a) makes a strong
case for changing the behavior and b) offers code that implements the new
behavior.
Personally, I think the current behavior is preferable. I don't want Xerces (or
any other tool) to perform time-consuming operations like fetching schemas and
validating documents unless I explicitly ask it to.

> Key: XERCESC-1736
> URL: https://issues.apache.org/jira/browse/XERCESC-1736
> Project: Xerces-C++
> Issue Type: Bug
> Components: Validating Parser (DTD), Validating Parser (Schema)
> (Xerces 1.5 or up only)
> Affects Versions: 2.7.0
> Environment: Windows XP professional
> Visual Studio 2005
> Reporter: Denis Tkachov
>
> Instances of both XercesDOMParser and SAX2XMLReader threat all the
> documents as valid even if a document does not match schema provided.
> In order if document does not match schema provided the library does not
> throw exception and getErrorCount method of the parser returns zero.
> So it seems to be a bug in the library.
> As example you can try this code:
> http://xml.apache.org/xerces-c/program-dom.html#ConstructXercesDOMParser
> Below are provided scheme and document (error marked with "does not match
> schema" comment) that reproduces error:
> datasetSchema.xsd:
> <?xml version="1.0" encoding="UTF-8" standalone="no"?>
