Unfortunately, XProc V1.0 defines all parameters as being of type "string" and XPath 2.0 doesn't provide automatic promotion of "string" values to any other sort of value. It's a nasty, unfortunate limitation in XProc 1.0, but I don't think there's anything we can do about it. The "solution" such as it is, is to change the stylesheet so that it accepts a parameter containing a string. It can then compare that string to "0" or "1" or "true" or "false" to determine the appropriate boolean value. Passing values on the command line (pre-XProc) is one of the reasons why, for example, the DocBook XSLT stylesheets define all "boolean" parameters as having the value "0" or "1" (as strings). Please let us know if you're unsatisified by this resolution. Be seeing you, norm -- Norman Walsh <ndw@nwalsh.com> | Life always comes to a bad end.--Marcel http://nwalsh.com/ | Aymé
