Hello

check such code on another site

img { replace: attr(src) }
img { link-longdesc: attr(longdesc) }
a { 
  link-set: attr(href);
  link-use: current;
}
base { link-base: attr(src)

Fictional example:

  <url>http://foo.bar</url>
  <title>foobar</title>

  url { set-link-source: content() }    
  title { use-link-source: current }

search articles about this in internet, but unfortunately don't understand :-(
can anybody explain, what mean this codes [attr(href);] [ link-use: current;] etc

thank you

attr stands for attribute
and the (item) between it is the set attribute for the anchor
