The &#xA; is coming from the fact you have a new-line in the 
stylesheet text node for the attribute.  Otherwise, it looks like 
your <image> element doesn't have a src= attribute.  Have you spelled 
it correctly?  Can you post a excerpt of your XML and the XSL-FO 
created for that XML?

Right ... but nothing is obviously wrong.  If you wanted to make 
things more succinct you could have used an attribute value template:

<fo:external-graphic content-width="scale-to-fit" content-height="100%"
                      width="100%" scaling="uniform"
                      src='url("{@src}")'/>

But other than that it looks fine to me (though I am bleary eyed in 
the middle of the morning).  I suspect you have a typo.
