Description Markus Schöpflin 2014-03-20 08:42:48 UTC 
Versions tested and affected: 2.9.1-2 (FC), 2.7.6-14 (CentOS)

Given the following schema:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="a" type="xsd:int"/>
</xsd:schema>

And the following document:

<a> 42</a>

Xmllint fails to validate this:

$ xmllint --schema test_schema.xml test_doc.xml 
<?xml version="1.0"?>
<a> 42</a>
test_doc.xml:1: element a: Schemas validity error : Element 'a': ' 42' is not a valid value of the atomic type 'xs:int'.
test_doc.xml fails to validate
Comment 1 Markus Schöpflin 2014-03-20 08:44:03 UTC 
According to XML Schema Part 2: Datatypes Second Edition, section 4.3.6 all atomic data types other than 'string' have their 'whiteSpace' constraint set to 'collapse', so I think the element 'a' should be valid.

There is even a comment to this effect in the libxml2 sources (xmlschemas.c / xmlSchemaTypeFixupWhitespace()): 

/* 
 * For all `atomic` datatypes other than string (and types `derived` 
 * by `restriction` from it) the value of whiteSpace is fixed to 
 * collapse 
 */

I am getting the same error for version: libxml2-2.9.3-3.fc24.x86_64

this is also my vote to give this one a little more priority ...
Comment 3 GNOME Infrastructure Team 2021-07-05 13:26:54 UTC 
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/libxml2/-/issues/

Thank you for your understanding and your help.
