      Description

      Error occurs in the combination of <fo:inline> of font-size="smaller"/"bigger"
      within <fo:block> of font-size in percentage. The error is "getBaselength
      called without context".

      <fo:block font-style="normal" font-size="80%" role="html:div"
      <fo:inline baseline-shift="super" font-size="smaller"
      role="html:sup">th</fo:inline>of each month.
      </fo:block>

      OK, now I see it too.

      I'll run it through the debugger, but already think I know what is going on.
      The property resolution mechanism tries to resolve to smaller/larger font-
      sizes too early. Percentages are resolved (mostly
      anyway) during the layout-stage, where FOP tries to already resolve
      the "smaller" keyword long before that.

      I haven't tried yet, but using em's could also lead to trouble in combination
      with percentages, as in:

      <fo:block>
      <fo:block font-size="80%">
      <fo:inline font-size="8em">

      Will keep you posted.

      Cheers
