In didn't expect this component to be this hard to understand which
obviously
means that I need to expand the description.

I have a document A that uses xinclude to include documents B and C.

Currently, the XInclude step would use the base URI of A to formulate
the absolute URI of B and C from the the xi:include element's href
attribute.  Let's call these uris URIB and URIC.  The regular xinclude
step would just read from URIB and URIC to perform the include.

This new component wouldn't read from URIB and URIC and instead
look at the sequence of documents provided on the 'documents'
port.  If it finds a document whose base URI is 'URIB' or 'URIC',
it will use them for the xinclude.  Otherwise, it will "fail" however
the xinclude spec says.

In general, this step includes from the sequence and only considers
"known" document to be those in the sequence provided on the
'documents' input port.  All other URI values are "not found".
