To be precise, mapping can be generated when template is set. For this nxdl entries must have src attribute:

#!xml
<!-- entry/hardware -->
<group type="NXcollection" name="D" src="tango://hzgpp05vme2:10000/p05/micos/D">
        <group type="NXlog" name="Position">
          <field type="float64" name="value">
            <dimensions rank="1">
              <dim index="0" value="0"/>
            </dimensions>
          </field>
          <field type="uint64" name="time">
            <dimensions rank="1">
              <dim index="0" value="0"/>
            </dimensions>
          </field>
        </group>
      </group>

This effectively maps to

tango://hzgpp05vme2:10000/p05/micos/D = /entry/hardware/D
