[Nexus] Antwort: Welcome to the "NeXus" mailing list (Digest mode)

[Pete Jemian]

Igor:

Both the intermediate files (schematron and XML) referenced in 
http://download.nexusformat.org/sphinx/validation.html are internal 
files of the NXvalidate code, not presented for access as part of NeXus. 
  The exact details of data file validation are provided in the source 
code of NXvalidate but are not yet present in the User Guide.

I take it as an assignment that we should create a library code for data 
file validation.  Also to document the validation process.  We can 
schedule both these for the upcoming code camp this fall.

In the repository, the nxdl.xsd file is one directory up from the 
various (base class, application, contributed) definitions.  You may 
find it necessary to also to have the file nxdlTypes.xsd.  There is yet 
another file, NeXus.xsd, that is not used now for data file validation.
