[xep-support] Getting XEP documents into another doc via external-graphic element

Hi there,

As I noticed that from xep 4.14 on there is the possibility to include xep documents as graphics.
I am however having lots of problems doing so where I do not know whether it's my lack of understanding of FO or whether it is faulty in some way.
Here is the line I use to get the XEP into the XSL:FO:
<fo:external-graphic id="20090421T153944.640-1216.51732.4841708.136d1" content-type="content-type:application/xepout" height="100mm" content-height="100mm" width="100mm" content-width="100mm" scaling="non-uniform" src="url(file:///C:/workingDir/output.xep)" vertical-align="top"/>

If I use the above tag, I get
error: formatting failed: java.lang.NullPointerException

If I use:
<fo:external-graphic id="20090421T153944.640-1216.51732.4841708.136d1" content-type="content-type:application/xepout" scaling="uniform" src="url(file:///C:/workingDir/output.xep)" vertical-align="top"/>

I get several errors "No space for an element, trying to recover", even if I try to put a 150mm x 110 mm XEP document somewhere on a 290mm x 210 mm doc.
So, what else might I be doing wrong? And can I tune the error-message output, so I get some stack trace for the above NullPointer?

Thank you in advance

Best Regards
Christian
