Deactivate adding empty namespace in merged tags

[vegaaaa]

There should be an option to be setable to not create the empty namespace on merged nodes when using a global xml namespace in the root node. I am not sure if that's actually a bug but it is annoying as a I need to remove the empty xmlns in the end of the merging again.

Problem:
Merging following xmls:

<?xml version="1.0" encoding="UTF-8"?>
<model xmlns="http://www.opengroup.org/xsd/archimate/3.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" identifier="model" version="1"
       xsi:schemaLocation="http://www.opengroup.org/xsd/archimate/3.0/">
    <name xml:lang="en-us">Test</name>
</model>

<?xml version="1.0" encoding="UTF-8"?>
<model xmlns="http://www.opengroup.org/xsd/archimate/3.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" identifier="model" version="1"
       xsi:schemaLocation="http://www.opengroup.org/xsd/archimate/3.0/">
    <elements>
        <element xsi:type="Device" identifier="ID2">
            <name xml:lang="en-us">Name</name>
            <documentation xml:lang="en-us">Test</documentation>
        </element>
    </elements>
</model>

Expected result:

<?xml version="1.0" encoding="UTF-8"?>
<model xmlns="http://www.opengroup.org/xsd/archimate/3.0/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" identifier="model" version="1"
       xsi:schemaLocation="http://www.opengroup.org/xsd/archimate/3.0/">
    <name xmlns="" xml:lang="en-us">String</name>
    <elements>
        ...
    </elements>
</model>

Actual:

<model ...>
    <elements xmlns="">
    ...
    </elements>
</model>

It need the elements tag to be without any namespace as it uses the globale namespace defined in the model.

Can you give any reason or updates on this?
