Generated with a Jinja2 template. The 'globs' variables come from the file globals.json containing global
variables/structures. The actual/dynamic data (cities) comes from the input CSV file cities.json.
Also a file with macros templates/macros.tpl.xml is imported, allowing reuse for common structures like INSPIRE id's.

Jinja2 custom Filter.
By specifying a target_crs we can even reproject from the source CRS.
The gml_format=GML2|GML3 determines the general GML form: e.g. pos/posList or coordinates. gml_longsrs=YES|NO
determines the srsName format like EPSG:4326 or urn:ogc:def:crs:EPSG::4326 (long).
