There is even a new ISO standard that defines the format for colour data
as ASCII as well as in XML format.
That's ISO 28178.

That sounds more likely, although it's not clear if by ASCII they
mean that it's CGATS, and in any case it seems as loose as CGATS:
"ISO 28178:2009 is intended to be used in conjunction with other
standards that will define the required data, and tags or keywords for
specific data exchange applications.".
The standard is expensive too, working against wide adoption.
I'm confused about the relation between CGATS.17, CxF / CxF 2 and ISO 28178
Moreover I was fairly disappointed by the CGATS.17 examples and demo
suites I've seen so far (e.g.
<http://www.npes.org/Standards/toolsdemosuite.html>): even though XML
based file formats (and parsers) are quite complex, there seems to be no
way to encode spectral measurements unambiguous and machine readable yet:
