how to reference custom codec in a package?

[Skip Montanaro]

I wrote a simple codec which strips accents from latin-1 characters (e.g.,
maps 'é' to 'e').  If it lives in a package how do I refer to it?  For
example, what should this statement look like 

    x = unicode(x, "latin1").encode("latscii")

if latscii.py lives in the spambayes package?  This seems to work:

    x = unicode(x, "latin1").encode("spambayes.latscii")

but is that the right way to do it?

Thx,

Skip
