Yes, the standard states those formatting objects must be empty, so the 
tool is reporting that to you.  Given that fo:external-graphic gets its 
information from its attributes, why do you not use an empty 
element?  Also, given fo:page-number-citation gets its characters for 
display from the formatting engine, it too has to be empty.

I believe the message is quite clear and unequivocal.

Note that:

   <fo:external-graphic ...attributes-here...>
   </fo:external-graphic>

is *not* an empty XML element because of the child text node.

>FOP seems to be leniant though if i amdoing something wrong..

I must say that "lenient" is not an adjective I've heard before when 
discussing the conformance issues with FOP.

I hope this helps.
