I wanted to emphasise a point that Thomas Kurz made. The 1992 standard was made publicly available for free. Therefore many implementors got hold of it and followed it, and discussion of behaviour could refer back to the standard to clarify what implementations should and should not be doing. It's fully in the spirit of Open Standard. The 2008 version of the standard is not bad. But you're meant to pay the ISO for a copy, and there are many limitations on posting quotes in public. As you can imagine, this greatly hampers discussion of behaviour and identification of bugs. Part 1 of the current standard, ISO/IEC 9075-1:2016, for example, is 78 pages long and costs CHF178 (= 150 Euro = US$180). I didn't look up all the prices, but part 14 (sic) is 444 (sic) pages long and costs CHF198 (= 170 Euro = US$200). I would encounter some difficulty in writing software to conform to a 444 page document if I couldn't discuss that document with people outside my organisation. Far from an Open Standard. Which is why you will rarely see it quoted.
