LogicalTerminationPoint::_(!)physicalPortReference need to be pruned

[PrathibaJee]

For the proposal in the issue openBackhaul/core#10 , need to prune the attribute LogicalTerminationPoint:physicalPortRefernce[*] from the CoreModel ,

Solution :
In the UML2YANG tool in the experimental branch ,

• need to remove the following template from the /models/tools/pruning-and-refactoring/core-model/src/main/resources/xslt/prune-and-refactor-core-model.xslt

<!-- To change the datatype of physical-port-reference from string to leafref to point to a instance in the equipment list -->
  <xsl:template match="ownedAttribute[@xmi:id = '_RLDi4BieEeSh8KVgZCMyDw' ]" >
    <xsl:copy>
      <xsl:apply-templates select="@*"/>
      <xsl:attribute name="type">_8SXNej-HEeaRI-H69PghuA</xsl:attribute>
      <xsl:attribute name="aggregation">shared</xsl:attribute>
      <xsl:attribute name="association">_X1qQMD-QEeaRI-H69PghuA</xsl:attribute>
      <xsl:apply-templates select="node()  | text()"/>
    </xsl:copy>
  </xsl:template>

• need to modify the field "Prune" to true for the attribute physical-port-reference in the /models/tools/pruning-and-refactoring/core-model/src/main/resources/xslt/pruning-control.xml.

<property id="_RLDi4BieEeSh8KVgZCMyDw" name="physicalPortReference" prune="true"/>
