Several methods that the standard templates use are not supported, these are:
self/root
Adding this code to the <head> of the /auth/ templates causes an error:
<link rel="shortcut icon" href="../../../css/favicon.ico" type="image/x-icon" petal:attributes="href string:${self/root/uri}favicon.ico" petal:condition="true: self/root/get --favicon.ico;" />
[PETAL ERROR] Cannot find value for 'get' at '/self/root': get cannot be retrieved
self/cgi/path_info_eq
This code causes an error:
<link rel="top" href="/" hreflang="en" title="Root Document" type="text/html" petal:attributes="href self/root/uri; hreflang self/root/lang; title self/root/title;" petal:condition="false: self/cgi/path_info_eq '/';" />
