Special features

  • File creation
  • Cryptographic functions

File creation

Several functions, associated at different namespaces, allow to create files on the engine side. They're all aliases to the xsltDocumentElem() function defined in libxslt/transform.c. The content written to the file must be valid UTF-8 (so plain ASCII works too). Existing files can be overwritten.
