<br>
The namespace "<a href="http://www.openspatial.net/wps" target="_blank">http://www.openspatial.net/wps</a>" is an old namespace and<br>
has been dropped (if you look at the WPS1.0.0 document you have it in<br>
the SOAP example in page 69).<br>
<br>
In the OGC world the schema structure takes precedence over<br>
documentation, meaning if it is in the schema then is an "absolute<br>
truth", and the WPS using that namespace should be updated.<br>
<br>
Luca, maybe you should use an "open mind" approach, using what ever<br>
namespace is assigned to wps. See the example below on how to get the<br>
namespace:<br>
<br>
<br>
import urllib, stringIO<br>
from lxml import etree<br>
xmlIO=urllib.read("<a href="http://schemas.opengis.net/wps/1.0.0/examples/53_wpsExecute_request_ComplexValue.xml" target="_blank">http://schemas.opengis.net/wps/1.0.0/examples/53_wpsExecute_request_ComplexValue.xml</a>")<br>
wpsXML=etree.parse(xmlIO)<br>
wpsXML.getroot().nsmap["wps"]<br>
>>'<a href="http://www.opengis.net/wps/1.0.0" target="_blank">http://www.opengis.net/wps/1.0.0</a>'<br>

I noticed that your service uses the namespace "<a href="http://www.opengeospatial.net/wps" target="_blank">http://www.opengeospatial.net/wps</a>", while the other two WPS services I have tested against use "<a href="http://www.opengis.net/wps/1.0.0" target="_blank">http://www.opengis.net/wps/1.0.0</a>".<br>
