[xep-support] Creating inline areas with zero width

[Janean Angeles]

Hi Jirka,

I'm not sure if this is the 'best' way of doing this, but it worked for me.  

Try applying a negative padding-left to the 2nd value.  Taking your fo and altering it like this:

<fo:block>
	A<fo:inline baseline-shift="super" inline-progression-dimension="0pt">X</fo:inline><fo:inline baseline-shift="sub" padding-left="-8pt">Y</fo:inline>
        </fo:block>

This technique worked in my test.  You may still have to play with the padding variable to get them right (due to font differences), but it's something to start with...

Hi,

I need to typeset both super- and subscripts in a way that they are 
aligned above, not placed one after another.

I need to get:

  X
A
  Y

not

  X
A
   Y

I thought that setting width (or inline-progression-dimension) to 0pt 
will not move typesetting point and I will get desired output by using:

<fo:block>
    A<fo:inline baseline-shift="super" 
inline-progression-dimension="0pt">X</fo:inline><fo:inline 
baseline-shift="sub">Y</fo:inline>
</fo:block>

 From my reading of XSL-FO it is not perfectly clear whether it is 
possible to set width of inline areas. Above example works in XSL 
Formatter, but not in XEP.

Is there any other workaround for creating "inline phantoms"?
