Data insert (without namespaces)

There is simplified and more efficient to sent Transaction data without full namespaces declaration, as in following example:

<Transaction
    xmlns="http://www.opengis.net/wfs"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    version="1.0.0"
    service="WFS"
    xmlns:p5_default_db="https://biuro.biall-net.pl/wfs/default_db"
    xmlns:gml="http://www.opengis.net/gml">
    <Insert xmlns="http://www.opengis.net/wfs">
        <p5_default_db:P5Automation1OrangeRaportSimple>
            <DEVICE_ID>1</DEVICE_ID>
            <IdPort>1</IdPort>
            <InputValued>2.2</InputValued>
            <PortCustName>Water Level</PortCustName>
         </p5_default_db:P5Automation1OrangeRaportSimple>
    </Insert>
    <Insert xmlns="http://www.opengis.net/wfs">
         <p5_default_db:P5Automation1OrangeRaportSimple>
            <DEVICE_ID>1</DEVICE_ID>
            <IdPort>2</IdPort>
            <InputValued>100</InputValued>
            <PortCustName>Battery Status</PortCustName>
         </p5_default_db:P5Automation1OrangeRaportSimple>
    </Insert>
</Transaction>

The result:

<?xml version="1.0" encoding="UTF-8"?>
<wfs:WFS_TransactionResponse version="1.0.0"
		xmlns:wfs="http://www.opengis.net/wfs"
		xmlns:ogc="http://www.opengis.net/ogc"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <wfs:InsertResult>
        <ogc:FeatureId fid="P5Automation1OrangeRaportSimple.2" xmlns:ogc="http://www.opengis.net/ogc"/>
        <ogc:FeatureId fid="P5Automation1OrangeRaportSimple.3" xmlns:ogc="http://www.opengis.net/ogc"/>
    </wfs:InsertResult>
    <wfs:TransactionResult>
        <wfs:Status>
            <wfs:SUCCESS/>
        </wfs:Status>
    </wfs:TransactionResult>
</wfs:WFS_TransactionResponse>
