well, this thing is really crazy...
when I change my extender declaration to include both adapters I am
getting a weird error:
class NITFExtender(object):
implements(ISchemaExtender, ISchemaModifier)
adapts(IATNewsItem)
this doesn't happens if I use implements(ISchemaExtender) or
implements(ISchemaModifier), but only if I use both at the same time.

this method I use to install this on Plone 2.5 and it was provided to me
by Erik Rose:
def installExtenderGloballyIfLocallyIsNotSupported(extenderClass, name):
"""If we're on a version of Plone that doesn't support local
adapters, make it so merely putting the extender in the Products folder
activates it across on all Plone sites."""
if not localAdaptersAreSupported:
from zope.component import provideAdapter
provideAdapter(extenderClass, name=name)
Erik?
