The AxKit::XSP::Util taglib includes some utility methods for including XML from the filesystem, from a URI, or as the return value from an expression. (Normally an expression would be rendered as plain text, so a "<" character would be encoded as "&lt;"). The AxKit utilities taglib is a direct copy of the Cocoon utilities taglib, and as such uses the same namespace as the Cocoon Util taglib, http://apache.org/xsp/util/v1.
