It is caused by the two vertical-align="center" (invalid attribute 
value; see https://www.w3.org/TR/xsl/#vertical-align) found in your 
"YYY.fo".

Replace these by (valid attribute value) vertical-align="middle" and 
you'll work around this bug.

We'll fix this bug by making XMLmind XSL-FO Converter more robust in the 
next version (v6.2).

In fact, Apache FOP 2.3 reports many errors, among them:
---
$ fop -r -fo YYYY.fo -pdf YYY.pdf

[ERROR] FOUserAgent - Invalid property value encountered in 
vertical-align="center": org.apache.fop.fo.expr.PropertyException: 
file:/home/hussein/src/xfc/BUG1/YYY.fo:356:27: No conversion defined 
center; property:'vertical-align' (See position 358:112)
...
---
(-r means: validity errors are not fatal.)
