I'm a little confused about the best way to change or override default

I'm less confused now ;-)
Out of the box the 'html' serializer is set to produce Transitional
4.01 HTML. So if I put the following in sitemap.xmap:
...
<map:serialize type="html"/>
...
then that's what I get.
Now if I try overriding the defaults by explicitly adding extra
parameters to the sitemap as follows:
...
<map:serialize type="html">
<doctype-public>-//W3C//DTD HTML 4.01//EN</doctype-public>
<doctype-system>http://www.w3.org/TR/html4/strict.dtd</doctype-system>
</map:serialize>
...
I get no change in the output. Is this because the spring beans which
define the default settings have a higher priority than the sitemap?
I realize now that doing things this way is the 'old' or pre-cocoon 2.2
way and I must empty my head of such thoughts!
As an experiment I located the following file:
[cocoontrunk]/core/cocoon-pipeline/cocoon-pipeline-components/src/main/resources/META-INF/cocoon/spring/cocoon-core-serializers.xml
which I believe to be the file responsible for setting the default
properties of the 'xml', 'html' and 'xhtml' serializers as well as some
others. I then copied this file to my own block here:
[myblock]/src/main/resources/META-INF/cocoon/spring/serializers.xml
I then edited this file to remove all the other bean definitions except
the one with the name:
'org.apache.cocoon.serialization.Serializer/html'. I also changed the
doctype-public and doctype-system to the HTML 4.01 strict definition.
After restarting my C2.2 application I was pleased to see that the
pipeline which had been outputting 4.01 loose doctype was now outputting
4.01 strict HTML as required.
So it works! I have successfully overridden the default config for a
Cocoon component without having to resort to the sitemap.xmap file.
Having read other user's comments on this I can see how useful this is.
