Problem summary
The legacy 'shading network material' location type has been deprecated in favour of 'material' locations, however, NetworkMaterialSplice seems to still create it which is unexpected.
Steps to reproduce
Create a PrmanShadingNode and set KatanaAlphaPhong as shader
Create a NetworkMaterialSplice
Connect the output of the PrmanShadingNode to the append port of the NetworkMaterialSplice
Look in the Scene Graph and Expand All. You should see a location under materials of type 'shading network material'
Reproduced by support
Reproduced in 1.6v3 and 2.5v1b1 so this is still current in the latest build and should be updated. Linux RHEL 6.
Expected behaviour
The NetworkMaterialSplice location created should be of type 'material'
Actual behaviour
The NetworkMaterialSplice location created is of type 'shading network material'
