Hello,
I am trying to create a GML with XML templater.
My reader is Shapefile format.

When I paste the sub-element template in the root template I don't have any errors (but then of course the file isn't valid).
However, I have the following error when I try to add a sub-element:
XMLTemplater(XMLTemplaterFactory): The following error occurred near line 19, column 6 of the query: 
XMLTemplater(XMLTemplaterFactory): "gml": can not expand namespace prefix to URI 
XMLTemplater(XMLTemplaterFactory): An error occurred while parsing the 'SUB' sub-template 
XMLTemplater(XMLTemplaterFactory): A fatal error has occurred. Check the logfile above for details A fatal error has occurred. Check the logfile above for details
XML templater:

With the following for the SUB template:
<?xml version="1.0" encoding="UTF-8"?>
<gml:FeatureCollection xmlns:za="http://osi.irisnetlab.be/gml" xmlns:gml="http://www.opengis.net/gml">    
<za:LayerNameFr>$(Layer_Name_FR)</za:LayerNameFr>    
<za:LayerNameNl>$(Layer_Name_NL)</za:LayerNameNl>    
{fme:process-features("SUB")}
</gml:FeatureCollection>And for the SUB template:
<gml:featureMember>
        <za:NameFr>Cluster n°{fme:get-attribute("NBCLUS")} - Responsable: {fme:get-attribute("resp")}</za:NameFr>
        <za:From>15/06/2019</za:From>
        <za:To>15/12/2019</za:To>
        <za:Comment>{fme:get-attribute("A_list_ws")}</za:Comment>
        <za:TypeZa>Autre</za:TypeZa>
        <gml:surfaceProperty>
          <gml:Surface srsName="EPSG:31370" srsDimension="2">
            <gml:patches>
              <gml:PolygonPatch>
                <gml:exterior>
                  <gml:LinearRing>
                    <gml:posList>{geom:get-points()}</gml:posList>
                  </gml:LinearRing>
                </gml:exterior>
              </gml:PolygonPatch>
            </gml:patches>
          </gml:Surface>
        </gml:surfaceProperty>
 </gml:featureMember>Could someone hint me in the right direction?
Thank you !
