Order changed when seriallized to string

[danhamill]

For this dictionary:

{'Name': 'Shear',
 'Type': 'RASResultsMap',
 'Checked': 'True',
 'Filename': '.\\Test Plan\\Shear Stress (08Aug2020 08 00 00).vrt',
 'MapParameters': [{'MapType': 'Shear',
   'LayerName': 'Shear Stress',
   'OutputMode': 'Stored Current Terrain',
   'StoredFilename': '.\\Test Plan\\Shear Stress (08Aug2020 08 00 00).vrt',
   'Terrain': 'CBR_041619',
   'ProfileIndex': '576',
   'ProfileName': '08Aug2020 08:00:00',
   'ArrivalDepth': '0'}]}

and this processor:

ras_processor = xml.dictionary('Layer',[
                                xml.string('.', attribute='Name'),
                                xml.string('.', attribute='Type'),
                                xml.string('.', attribute='Checked'),
                                xml.string('.', attribute='Filename'),
                                xml.array(xml.dictionary('MapParameters', [
                                    xml.string('.', attribute = "MapType"),
                                    xml.string('.', attribute = 'LayerName'),
                                    xml.string('.', attribute = 'OutputMode'),
                                    xml.string('.', attribute = 'StoredFilename'),
                                    xml.string('.', attribute = 'Terrain'),
                                    xml.string('.', attribute = 'ProfileIndex'),
                                    xml.string('.', attribute = 'ProfileName'),
                                    xml.string('.', attribute = 'ArrivalDepth')
                                    ])
                                    )])

After I run xml.serialize_to_string(ras_processor, test, indent=' '). The order of the attributes has changed to alphabetical. I would prefer to have the same attribute order as the input dictionary. Can this be done?

<?xml version="1.0" encoding="utf-8"?>
<Layer Checked="True" Filename=".\Test Plan\Shear Stress (08Aug2020 08 00 00).vrt" Name="Shear" Type="RASResultsMap">
    <MapParameters ArrivalDepth="0" LayerName="Shear Stress" MapType="Shear" OutputMode="Stored Current Terrain" ProfileIndex="576" ProfileName="08Aug2020 08:00:00" StoredFilename=".\Test Plan\Shear Stress (08Aug2020 08 00 00).vrt" Terrain="CBR_041619"/>
</Layer>

Thanks!
