fo:inline border question

Dear all

I have reproduced the problem I have in a much smaller scale. I have something like the code below. When using Antenna House Formatter the fo:inline elements containg the text "text2" are not vertically aligned because the second one is surrounded by an aditional fo:inline element. I have tried using different types of settings for the additional fo:inline but have been unable to get the texts aligned. 

At this point I do not know if it is an Antenna House implementation issue. I have read the spec but have been unable to understand whether it should be possible to have an inline free of borders/margins/spaces. Should it be possible?

I thank you in advance.
