Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.

Points to the path of the last element in the geometry chain that places this object in space. When followed through that chain is supposed to end at an element depending on “.” i.e. the origin of the coordinate system. If desired the location of the slit can also be described relative to an NXbeam, which will allow a simple description of a non-centred pinhole.
The reference direction of the pinhole is parallel with the z axis. The reference point of the pinhole is its center in the x and y axis. The reference point on the z axis is the plane which overlaps the side of the opening of the pin hole pointing towards the source (minus on the z axis).
diameter: (optional) NX_NUMBER {units=NX_LENGTH}
Size of the circular hole defining the transmitted beam size.
TRANSFORMATIONS: (optional) NXtransformations

This is the group recommended for holding the chain of translation and rotation operations necessary to position the component within the instrument. The dependency chain may however traverse similar groups in other component groups.
