Xsd to RNG to RNC Conversion problem.

I am trying to compile a conforming XML schema to an rnc for use with
nxml.
I do the following:

1. Compile the Xsd to rng with rngconv.jar from
the Sun Multi-Schema XML Validator.
This appear to go correctly (except for some
'"anyType" is implicitly used ...' warnings).

2. I then convert the rng to rnc using trang or
using the or RngToRncText.xsl and the cygwin xsltproc

3. When I then attempt to load the .rnc with rng-c-load-schema
I get the following error message:

Incorrect Schema:"...nxml-mode/schema/xanx.rnc"
4318 "Expected `}' but got `+'

I have two questions:

1. How do I convert the token count into a
line the the rnc produced? I have seen this problem before
and by shear elimination have managed to get the rnc to
work, but would like a better way.

2. More to the point does this indicate some problem
with the xsd or the rng converter?
