probably no one tried using the hex literal form so never noticed the

I think this list is it although I agree the website, and prefereably
the document itself ought to have said /say that.

I'm sure the intention was to allow multiple spaces here, so that's a

I guess so, although I wonder if there was an explict decision to change
this for OM2 and just allow decimal, but that got implemented in the
schema but not the text. I suppose I should try to search for minutes of
meetings around that time... On the other hand since the text of the
standard has stood for so long now, perhaps we should stick with hex
even if the intention was to drop it and change the schema as you
suggest, I suppose
pattern = "(\s*(-\s*)?[0-9]+(\s|[0-9]+)*) | (\s*(-\s*)?x\s*[0-9A-F]+(\s|[0-9A-F]+)*)"}}
