Re: [ubl-ndrsc] Removing use of "-" in element and type names

The only general naming rule we have that sort of covers this is:

[R5] XML names constructed from dictionary entry names must not include
periods, spaces, or other separators.

This has been part of the NDR document from the beginning.  If this means we
have put in hyphens, then we are not compliant to our own rules.
