Subject: [PATCH] The patch of Irene to allow MathML presentation inside <m:ci>
 was not correct. As a consequence (but there were worst ones) hyperlinks were
 not created to sub-scripted identifiers. I have changed the patch. Though, I
 am not sure it is the correct one. In particular, what happens if I put
 content markup inside the m:ci? (It was recursively processed in the original
 stylesheet)
