I think I've understand something:

If you use components by role, you just give the class name in parameter,
and the component manager will create a new instance at each request.
If you use components by name, the component manager will return a single
instance (that will be shared).

Am I right ?

And I've got another question:
If you want to give parameters to a component, you write, in the config
file, something like
<parameter name="..." value="..."/>
But if you want to give it a list of classes, without "names", what is the
"good" way of doing it ?

Ex.:
    ImageReaders are classes that read image headers, check if it is an
image type it can handle, and read the width and height.

  <component role="image-reader-factory"
class="org.apache.fop.image.analyser.ImageReaderFactory">
    <image-reader class="org.apache.fop.image.analyser.GIFReader"/>
    <image-reader class="org.apache.fop.image.analyser.JPEGReader"/>
    <image-reader class="org.apache.fop.image.analyser.PNGReader"/>
    <image-reader class="org.apache.fop.image.analyser.BMPReader"/>
  </component>

This factory needs parameters, but it's just a list of classes, and not
named parameters.
