Hi Roland...

In general, you have to let FME know what attributes are being added
onto features as they exit each output on the transformer. There are a
couple ways this can be done:
1) Any parameter with a NEW_ATTR type will add an attribute as given by
the user. See the SpatialFilter for an example.
2) The ATTRIBUTES_ADDED section can be used to add attributes onto a
given output. See the SurfaceModeller for an example.
You are right when you say that some of the transformers are "special".
Workbench has some special code that allows the AttributePrefixer (and
others) to do their magic and add these attributes dynamically. It is
difficult to say how you can get the output attributes you want without
knowing what your specific problem is. Could you email the transformer
definition and a description of what you're trying to achieve to our
support team?
As an aside, while we don't prevent anyone from writing .fmx files by
hand, we don't really encourage it. Since FME 2006 you can make custom
transformers entirely using the Workbench interface, building from
existing transformers, and they become usable like any other
transformer. You can make one by selecting File -> New -> Create a
custom transformer. This may be an easier way to build your tool then
trying to write a .fmx file by hand. If you can't use this to build
your tool, let us know what you're trying to do and we'll see what we
can do to make it happen.
