Of course serializers do transformations, you already wrote it: from SAX

serializer (and at the end the output) is absolutely predictable. If you
feed the same SAX events into a specific serializer you will always get
the same result.
So the behavior of a transformer is not absolutely predictable ? If i feed
my xsl transformers with the same stylesheet and the same data, the result
is hopefully the same. I hope that predictability is a quality shared not
only among serializers but by all cocoon components ;-).
You know what I meant: A serializer just changes the representation of
the data but does not change the data itself - while this is of course
not true for the transformers. When you setup your pipeline it is a
1:1-relation of SAX input to byte output and does not depend on anything
else. Your serializer breaks this.
And to come back to Antonio's absolutely correct interjection about the
virtual serializers: This is the point were you can put together again
the above mentioned additional transformer steps and the standard
serializer.
He was just wondering if this thread was about virtual serialization. It's
not.
It is not, but if you break your stylesheet into multiple steps
(transformer(s) + standard serializer), you can put them together into a
virtual serializer.
