Doh, during the holiday I coded the builder I was talking about almost
fully (it just misses support for text and raster symbolizers).
I don't have the code handy right now but I'll post it tomorrow or
Monday. Where is yours so that I can have a look at it?
Here is the builder I've been working on. It's still quite green,
has just one test, misses the builders for text and raster symbolizers,
but you should get the idea anyways.
Cheers

+- some default objects are missing in our API
+- text and raster symbolizer builders are missing
+- deal with the few deprecated items
+- should the builder validate the inputs? (null URL, negative scales?)
+- shall we build the upper layer as well (StyledLayerDescriptorBuilder?)
+- pass down the style factory from parent to child and have each
+ accept it in the constructor as well
