I have submitted PR <https://github.com/winlibs/libxml2/pull/2>.
I'm suspending this ticket until the issue will be fixed with a
new libxml2 release.

I can reproduce the issue as of PHP 5.6.23. The culprit is libxml2
2.9.4, which introduced a severe regression with regard to XSD
schema validation[1].
As libxml2 2.9.4 fixed several security issues, I don't think it
would be good to switch back to 2.9.3 for now, but perhaps a
bugfix in winlibs/libxml2[2] would be appropriate, so that PHP
5.6.26+ could be shipped with working XSD validation even if no
new libxml2 version would be released in the meantime).

Thanks for looking at this,
I saw the point increase of libXMl2, but I'm running on Windows pre-build binaries, so can not
change the build.
I have sent sample files via email from my work's email

There haven't been any relevant changes to XMLReader for years (at
least in the PHP-5.6 branch)[1]. The behavioral change might
simply be caused by an updated libxml.
Anyhow, it would be helpful if you could make sample XML and XSD
files available.
