[xml] [Patch] complex type extension cardinality mismatch


It seems that there is an issue regarding the inheritance of cardinality in complex type extension.
I have attached a simple XML file with the corresponding XSD, where "ItemWithNumber" is
a complexType extending the base type "Item". "Item" contains a unbounded sequence of "Name"
elements, but libxml2/xmllint does not allow more than one "Name" in the elements
 of type "ItemWithNumber" present in the XML. I may be mistaken, but I think it is not the expected behavior.
By the way, it seems that someone has already opened a bug related to the same problem in bugzilla #609796
 (https://bugzilla.gnome.org/show_bug.cgi?id=609796) "Failure to validate optional element in complex type 

The following patch fixes the validation of both my test case and the one reported in bugzilla #609796.

Please let me know if you need more information regarding this issue.
