Yeah, so Batik uses it for only two things: DOM Level 3 XPath functionality, as Jeremias mentioned (for 1.1 or 1.2 documents) and sXBL XPath selector syntax, which is only in 1.2 documents. The former is only needed if those DOM Level 3 XPath functions are called from script. The latter is hardly used at all, and will have to be reworked to be XBL 2.0 in the future anyway, which doesn’t use XPath for bindings. Does FOP allow documents to run script before being included in the resulting PDF (like with the -onload switch to the Batik rasteriser)? If not, then it’ll be completely safe to omit xalan. Leaving it out should only cause linker problems when such scripts are run, anyway, not for arbitrary documents. We could rework Batik to use recent JAXP XPath functionality if that is present, or Xalan if that is present, or fail gracefully otherwise. -- Cameron McCormack, http://mcc.id.au/ xmpp:[EMAIL PROTECTED] ▪ ICQ 26955922 ▪ MSN [EMAIL PROTECTED]
