This misses my point.  We have two components to NeXus:
[1] the standard, defined by NXDL (nxdl.xsd and the .nxdl.xml files)
[2] the NAPI, implemented in several languages

It is not possible to provide the implementation of NXformula in the 
standard.  The NAPI is the logical place to implement this.  Since the 
NAPI is not used by everyone, how can we ensure a commitment to 
implement it from those who do not use the NAPI?

Or, perhaps you suggest that implementation of NXformula be implemented 
in the NAPI and that implementation is used (perhaps with Python 
examples) to demonstrate examples to the part of the community that does 
not use the NAPI to read NeXus data files?
