Copying is obviously not allowed. But that copyright holders are able to 
prevent citation of extracts surprises me. I'm used to German law § 51 
UrhG, which explicitly allows citing excerpts of copyrighted material 
without acknowledgement from authors (with some if's and when's, but 
should apply here). Is this different in other countries? How does this 
work on international stage?

In [0], ISO/IEC allow citation conditionally. See "Extracting parts of a 
standard for inclusion in the company's internal documentation, user’s 
guide or manuals", and "Including parts of a standard in books or 
software applications". Anyway, would be really sad if we're not allowed 
to do it.
