Yes, types from "com.foobar" would be excluded as well. I'm not sure it
was intended but we should not change the behaviour due to backwards
compatibility...

Yep, check also the schema file (beans_1_1.xsd).

"if-class-available" is described above the example and in xsd. The
filter is active only if the classloader for the bean archive CAN
load a class for that name. So the filter will not be active if the
"Model" class can't be loaded or if the system property "exclude-ejbs"
is not set.

In any case the description of the example is not complete and we should
add a TCK test for this as well (AFAIK
org.jboss.cdi.tck.tests.deployment.exclude.ExcludeFiltersTest is not
testing multiple child elements).
