Maybe other/better ways to work around the > problem? I had the same concerns with grepping through the sources. For URLs, the solution is very easy. Use the following two parameters: * $ulink.hyphenate Set it to the ZERO WIDTH SPACE character (​ or ​). By default, it is empty. * $ulink.hyphenate.chars Defines which characters are considered to contain the ZWS after that character. By default, it's "/", but you could extend it with other characters like "_", "-", "&", ... These two parameters are used in the "hyphenate-url" template. This template goes through the string and checks each character, if it's in the set of $ulink.hyphenate.chars. You could use this template as a base for your <option> template. You can find an example of my modification of hyphenate-url in the daps repository. I needed a finer control which characters should contain the ZWS before or after that character. You can find the code here: https://svn.code.sf.net/p/daps/svn/trunk/daps/suse/xslt/fo/hyphenate-url.xsl Hope this helps. :) -- Gruß/Regards, Thomas Schraitle
