Bug : LNodeTypeAdapter.getDataAttributeRef should not throw exception "Multiple Data Attribute found"

[massifben]

Actual

I get an Exception when calling lNodeTypeAdapter.getDataAttributeRef("Do1.da1") on this SCL :

<SCL xmlns="http://www.iec.ch/61850/2003/SCL" version="2007" revision="B" release="4">
    <Header id="HeaderID" version="version" revision="Revision" toolID="toolID"/>
    <DataTypeTemplates>
        <LNodeType id="LN1" lnClass="ANCR">
            <DO name="Do1" type="DO1"/>
        </LNodeType>
        <DOType cdc="WYE" id="DO1">
            <SDO name="sdo1" type="SDO1"/>
            <SDO name="sdo2" type="SDO1"/>
            <DA name="da1" bType="BOOLEAN" fc="ST"/>
            <DA name="unused" bType="BOOLEAN" fc="ST"/>
        </DOType>
        <DOType cdc="WYE" id="SDO1">
            <DA name="da1" bType="BOOLEAN" fc="ST"/>
            <DA name="unused" bType="BOOLEAN" fc="ST"/>
        </DOType>
    </DataTypeTemplates>
</SCL>

The Exception is :

org.lfenergy.compas.sct.commons.exception.ScdException: Multiple Data Attribute found for this data reference Do1.da1 in LNodeType.lnClass=ANCR, LNodeType.id=LN1. Found DA : Do1.sdo1.da1, Do1.sdo2.da1, Do1.da1 

Expected

I expect the method to not throw Exception and return DataAttributeRef Do1.da1.
