Steven, sorry for annoying you. I see I was wrong in my treatment
of inline-rules with length="auto". Can you confirm or reject my revised
interpretation of "equalized length" behaviour:

  rule length for <fo:inline-rule length="auto"> is calculated *after* all
  other inline sequences on the line are formatted. The remaining free
  space is divided equally between all such elements on the line.

I have a couple of further questions on this:
1) Is there any lower limit for the rule length? I mean, if the remaining
   free space is zero, do we really need to suppress the correspondent
   elements? We could require the length to be not less than the
   rule-thickness, or link it  somehow to the current font metrics - I don't
   have any idea.
2) What about making 'length' a composite property, with max/min/opt/etc
   like in space-*?
