[LiveSky.com] Invalid XML file - OAL export

Export OAL - XML file is not valid.  In section target / position  in ra and de missing  part unit.

For example, this is exported (the error has been here since summer 2021 and applies to all objects):

        <target id="id_4_0_555_3674937295934386836" xsi:type="oal:deepSkyPN">
            <datasource><![CDATA[SkySafari]]></datasource>
            <name><![CDATA[NGC 6210]]></name>
            <alias><![CDATA[NGC 6210]]></alias>
            <alias><![CDATA[ARO 5]]></alias>
            <alias><![CDATA[PK 043+37.1]]></alias>
            <alias><![CDATA[PN G043.1+37.7]]></alias>
            <position>
                <ra><![CDATA[4.3747188590229715]]></ra>
                <dec><![CDATA[0.8206809010547005]]></dec>
            </position>
        </target>

Correctly it should probably be like this:

        <target id="id_4_0_555_3674937295934386836" xsi:type="oal:deepSkyPN">
            <datasource><![CDATA[SkySafari]]></datasource>
            <name><![CDATA[NGC 6210]]></name>
            <alias><![CDATA[NGC 6210]]></alias>
            <alias><![CDATA[ARO 5]]></alias>
            <alias><![CDATA[PK 043+37.1]]></alias>
            <alias><![CDATA[PN G043.1+37.7]]></alias>
            <position>
                <ra unit="arcsec"><![CDATA[4.3747188590229715]]></ra>
                <dec unit="arcsec"><![CDATA[0.8206809010547005]]></dec>
            </position>
        </target>

Value of unit according to oal_Base.xsd enumeration:

    <!-- angle units used in this schema -->
    <xsd:simpleType name="angleUnit">
        <xsd:restriction base="xsd:string">
            <xsd:enumeration value="arcsec"/>
            <xsd:enumeration value="arcmin"/>
            <xsd:enumeration value="deg"/>
            <xsd:enumeration value="rad"/>
        </xsd:restriction>
    </xsd:simpleType>

Thanks for support.
