Why is scomp trying to access remote url without -dl option set?

I've been using scomp successfully for years (currently XMLBeans 2.4.0).

Recently I got the following error:

  $ scomp -d genDir -src genDir -javasource 1.5 -out my.jar my.xsd
my.xsdconfig
  {...snip...}
  [ERROR] java.lang.RuntimeException: java.lang.RuntimeException: 
  org.apache.ws.commons.schema.XmlSchemaException: 
  Server returned HTTP response code: 503 for URL:
http://www.w3.org/2001/xml.xsd

Why was/is scomp trying to retrieve http://www.w3.org/2001/xml.xsd?

According to the scomp help, scomp should never try to download anything
over 
the network unless you explicitly set -dl option:
    -dl - permit network downloads for imports and includes (default is
off)

I'm *NOT* using the -dl switch, so why was/is scomp trying to download
this file?

Fortunately, the web server at http://www.w3.org stopped returning 503,
and my 
builds now work again.  But I don't want to be dependent on internet
resources at 
build time.   Why was/is scomp trying to fetch any remote resource
without 
the -dl option set?
