No and no. It does not seem like correct behavior, and at this point, I do not
suspect an issue in your environment.

That I cannot immediately judge. However, it definitely does not seem like this
possibility was taken into account when developing the extension.

Ideally, that should be the case. This I could already trace down. The code
that constructs the image from the URI in the case of fo:external-graphic
strips off the url() function call before handing the URI over to the
ImageManager, while fox:external-document passes the specified value, untreated.
The fix for part 2) is a simple modification that affects one line of code.
org.apache.fop.layoutmgr.ExternalDocumentLayoutManager, line 95, should become:
String uri = URISpecification.getURL(getExternalDocument().getSrc());
That should fix the cases:
<fox:external-document content-type="pdf" src="url('...')"/>
Part 1) I am not 100% sure of. Judging from the code in
ExternalDocumentLayoutManager, I would say some modifications may be necessary
there to cater for the possibility of a Data URI as well.
