I wrote this taglib a couple of years back; I'm not sure Seraph is still maintained, but if it is and if there's interest in this, I'd like to donate it (mostly for lack of usage and maintainance by myself currently)

Some minimal documenation is available at:
http://berkano.codehaus.org/Berkano+Seraph+Taglib

Code is visible at :
http://fisheye.codehaus.org/changelog/berkano/trunk/berkano-user/berkano-seraph-taglib

Binaries, sources and javadoc jars:
http://repo1.maven.org/maven2/net/incongru/berkano/berkano-seraph-taglib/1.0.0/

Cheers !
