Re: fluctuating baseline of header text

["j. van den hoff" <veedeehjay@googlemail.com>]

coming back to this again, if one uses old-style numerals for the page  
numbering the "problem" is aggravated:

\showframe\showglyphs
\definefontfeature [default] [default] [onum=yes]
\definefontfamily [mainface] [serif] [garamondno8]
\setupbodyfont[mainface,12pt]
\setupheader      [style=\smallbodyfont\ss\it]
\setupheadertexts [section]
\setuppagenumbering[location={header,margin}, style=\bfc]

\starttext
\dorecurse{97}{\section{Introduction}
bla
\page[yes]}
\stoptext

now, it also is obious that the "baseline jumps" occur in the page numbers  
themselves (caused mainly by the
large extension of the `6') so going, e.g., from page 25 to 26 the `2'  
jumps downward quite a bit. I understand
that this is unavoidable if the positions are determined as they seemingly  
are (measuring from the top and separately
for each page). what I at least would think to be nicer would be a  
situation where the baseline is determined for
the _whole_ document as the minimum (lowest position on page) of all  
page-wise baselines (that would be determined by the digit `6' in the  
present example)
and then using _that_ baseline for all headers and page numbers which  
would eliminate the jittering of header lines and page numbers.

I am aware that this will not always be the desired behaviour and that  
there might be documents where header layout might not be identical  
document wide,
so it might open a can of worms, but for most book-type documents I would  
think this to be reasonable and desirable.

my questions:

-- would that (a common baseline for the text in all the page headers) be  
better or worse than the present behaviour from a typographical point of  
view?
-- if desirable, could/should it be done?
-- could such behaviour be achieved presently with some clever trick?
