srsDimension is not read from parent element

[xdml]

These are not read correctly by pygml

as srsDimension is specified for parent element and not for <gml:posList/> element...

The example <gml:Polygon/> polygon will result in correct object, as srsDimension="2", but the pygml should take care of parents srsDimension attribute.
