Yes, it my have sense.
As far as I know we do not have a standard way to provide extensions to
plugins, if anyone on the list has some suggestion please chime in,

as a mojo parameter

If you mean 'forking' the plugin I think it won't be a good idea, as your
fork won't receive updates from the community version

I don't have the plugin in mind. The plugin contains two modules -
maven-jxr and maven-jxr-plugin. I would like to use the former to
generate the HTML report but use it in my own plugin. Having the option
to annotate the reports made by JXR plugin might have value but it is
outside the scope of what I want to do.
What I have in mind is to modify JavaCodeTransform to make it
extensible(or plugable). The way it works now is to use a chain of
filters to generate the markup, but this chain is hard-coded. For
example you can't easily wrap a single line inside span tag. The filters
are implemented as private methods inside JavaCodeTransfor. A simple
change as making them protected would allow classes that extend
JavaCodeTransform to modify the generated markup.

Not the entire code base, only JavaCodeTransform .
p.s. Enrico, sorry for spamming you with personal mail. I need to pay more
attention to how the "reply" button works :)
