A value that begins or ends with a pipe (\"| cmd\", \"cmd |\") is run as a command rather than opened as a file, and one that begins with a redirect (\"> path\", \">> path\") opens that path for write or append. to_file forwards its path argument to to_pdf and reaches the same read.\n\nAny caller that forwards untrusted input as the output path or as a stylesheets entry can run a command under the process UID; with the \"cmd |\" form the command's output is returned in place of the PDF, and with the \"> path\" form the named file is truncated. Stylesheets may only be added to an HTML source, so a URL or file source exposes the output path alone."
