(test-fn (complement #'starts-with-scheme-p)))
|Function: Reads an (X)HTML document from *STANDARD-INPUT* and writes it back to *STANDARD-OUTPUT*. Any attribute value which is in one of the positions denoted by *URL-REWRITE-TAGS* is rewritten by REWRITE-FN if it passes the test denoted by the optional function TEST-FN which defaults to the complement of STARTS-WITH-SCHEME-P. This function aims to yield correct results for correct (X)HTML input and it also tries hard to never signal an error although it may warn if it encounters syntax errors. It will NOT detect any possible error nor is there any warranty that it will work correctly with faulty input.
