I'm sure there is a programmatic interface to compute the length of a
string, but I'm rather looking for a way to specify it directly in the xml
file in a font-independant manner : in LaTeX, there a two units, called em
and ex, that represents the width of the M and x letters in the current
font. With this, it is possible to specify lengths that more or less "adapt"
to the chosen font.

Unfortunately, the field width is stored inside an attribute: the syntax of
these attributes is not documented in a DTD...
