XML Schema validation error on valid instance

Good day,

I am writing a small XML Schema validation benchmark (so far
libxml2 kicks
ass of all general-purpose validating XML parsers for C/C++
that I could
get my hand on) and stumbled upon this bug in libxml2 2.6.26
(Debian
unstable). The attached test.xml, when parsed and validated
with libxml2,
results in the following error:

Schemas validity error : Element '{http://www.codesynthesis.com/xmlns/xsdbench/structure}p
each': This element is not expected. Expected is one of (
{http://www.codesynthesis.com/xmlns/xsdbench/structure}a
pple, {http://www.codesynthesis.com/xmlns/xsdbench/structure}o
range, {http://www.codesynthesis.com/xmlns/xsdbench/structure}m
ango ).

hth,
-boris
