Hi Mark,

then we should say that our examples uses an older representation. But I think 
it's better to change the example code. We could use something like that

CREATE DOMAIN DFLAG AS SMALLINT DEFAULT 0 NOT NULL
  CHECK (VALUE=-1 OR VALUE=0 OR VALUE=1);

-- ISO values of DSLR cameras --
CREATE DOMAIN DCAM_ISO AS SMALLINT;

-- Integer Kelvin value --
CREATE DOMAIN KELVIN AS SMALLINT;

I think we should „correct“ it.


Some of the older RGB schemes are 16 bit, eg see 
https://en.wikipedia.org/wiki/List_of_monochrome_and_RGB_color_formats#16-bit_RGB

Correct :-)

Nothing dramatic, but a more logical example would be better.
