as_sld function

When I go to print my sld out my filter ends up below my symbolizer. Is there any way to avoid since this violates sld styling policies? Here is my code.

mysld = sld.StyledLayerDescriptor()
nl = mysld.create_namedlayer('test')
ustyle = nl.create_userstyle()
fts = ustyle.create_featuretypestyle()
firstRule = fts.create_rule('test',sld.PolygonSymbolizer)
firstRule.create_filter('value', '>', 'T')
print mysld.as_sld(pretty_print=True)

Start by inspecting the as_sld(pretty_print=True) entry point used in the example and reproduce the generated SLD ordering with the shown filter and PolygonSymbolizer. Compare the output with the required styling order; done means the filter is emitted in the correct position relative to the symbolizer and the existing output behavior remains covered.
