No: you can access map:parameter elements from within Java code in the 
same way how this is done in the XSLTTransformer [1]: consider that 
"source" is the only pre-defined parameter you have in any pipeline 
component, mapped to the 'src' XML attribute.

Not that I know: anyway I am using similar includes in different 
production environments with high load and I've experienced no troubles 
so far.

They are lost: you need to explicitly pass them though.
