    As a follow-up to my previous message a small correction just to make
    it clear: you cannot mix percents and absolute values only in the
    circumstances when formatter must have layout specific information
    beforehand, i.e. when calculating containers widths etc. That is
    exactly the case with your code since XEP complains about mixed
    expression in specification of inline-progression-dimension (width).

    MS>> Hi,

    MS>> I ran into a problem today with XEP 3.8. I have some reasonably complex

    MS>> an expression of the form:

    MS>> "100% - -5.4pt"

    MS>> in my XSL file.

    MS>> I had a look at the grammar defined in the XSL specification, and as far

    MS>> XEP says this, though:

    MS>> XEP Warning: Bad attribute inline-progression-dimension: Could not
    MS>> evaluate expression (100.0% - -5.386pt) in attribute
    MS>> inline-progression-dimension.maximum

    MS>> I can work around this for the moment, but I'd appreciate anyone a bit
    MS>> more knowledgeable about this stuff letting me know if my original
    MS>> version was legal (i.e. is this an XEP bug?)
