  Models for the diffuse Galactic continuum emission and synchrotron radiation
show that it is difficult to reproduce observations of both of these from the
same population of cosmic-ray electrons. This indicates that an important
contributor to the emission below 10 MeV could be an unresolved point-source
population. We suggest that these could be Crab-like sources in the inner
Galaxy. Alternatively a sharp upturn in the electron spectrum below 200 MeV is
required.
