cad102b861f74d56e3f6e710c466cf1a38a5db56 broke validation of spreadsheets
against the ODS relaxng spec.

Start by getting the spec:
# wget http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-ext-schema.rng
[...]
# sha1sum OpenDocument-v1.2-os-schema.rng
adc746cbb415ac3a17199442a15b38a5858fc7ef  OpenDocument-v1.2-os-schema.rng

This contains the fragment

	<define name="namespacedToken">
		<data type="QName">
			<param name="pattern">[^:]+:[^:]+</param>
		</data>
	</define>

which used to match names like "gnm:spinbutton", but after the above commit
does not.  The regexp match is done only on the "spinbutton" part, so no
match.

I don't know if the ods relaxng spec is wrong or if xmllint is at fault.

The error message from xmllint is misleading.  That's common with relaxng
validation:
# xmllint --noout --relaxng ods-schema/OpenDocument-v1.2-os-ext-schema.rng  ~/c-save.xml
/home/welinder/c-save.xml:10: element forms: Relax-NG validity error : Expecting element table-column-group, got forms
/home/welinder/c-save.xml:10: element forms: Relax-NG validity error : Did not expect element forms there
/home/welinder/c-save.xml:10: element forms: Relax-NG validity error : Expecting element table-header-columns, got forms
/home/welinder/c-save.xml:10: element forms: Relax-NG validity error : Element table failed to validate content
/home/welinder/c-save.xml fails to validate

The document in question follows.  This is a reduced document for the purpose
of this bug report, not a meaningful spreadsheet file.
