First architectural changes
compound document: 1st version getting the content-type of each document
and filtering only the html/xml
2nd version without checking the content-type because it's too slow
clean up
use standard markup validator instead of validator.nu to check HTML4 and
XHTML documents
forgot 'done()' at the end of the rule

'simple validation' and 'recursive validation'
