Is there any known interoperable issues about using Axis1 to consume CXF's webservices?

[Damon]

Hi all:
    The reason i have to use Axis1 is for old services using rpc/encoded.
    Now i have to consider the interoperable problems, and CXF seems like the 
most popular web services framework for now, so any possible issues would 
happen if i use Axis1 to consume CXF webservices?
   I only found one in google: using Axis1 consume XPOM/XOT CXF webservices..
   And just in case, is there any solution for CXF support rpc/encoded binding?

Regards
