Comment(by aperi2007):

 mmh....
 I guess probably no, but I'm not sure of this.

 I see these reports that say all the changes between libxml2 versions.

 [http://upstream-tracker.org/versions/libxml2.html]

 As it say the only two suspectable release that could break compatibility
 are
 2.6.22 to 2.6.23
 and
 2.8.0 to 2.9.0

 The total incompatibility are about 6.58&%
 as reported from here.
 [http://upstream-
 tracker.org/compat_reports/libxml2/2.6.22_to_2.6.23/abi_compat_report.html#Medium_Risk_Problems]
 [http://upstream-
 tracker.org/compat_reports/libxml2/2.8.0_to_2.9.0/abi_compat_report.html#Medium_Risk_Problems]

 So I guess it is pretty incompatibility.

 So perhaps libxml 2.9.0 is not a good update as is.

 But tinyows 1.0.0 rc4 is really used as is now on ogeo4w ?

 The previsous version of libxml2 has a knowed GML bug that need to do some
 manual changes on libxml2 himself to use with tinyows (rc4 also).
 [http://mapserver.org/trunk/tinyows/libxmlschemagmlbug.html]

 So perhaps just now is the tinyows 1.0.0 rc4 that don't work very well
 with a libxml2 2.6 is that library was not manual patched ?
