"sandboxing" elements: property name

[Mouvedia]

//for @container
base: yes | (no);
//for @root
base: (yes) | no;

Behavior

This property will be on by default on the document element if an HSS file is loaded with an XML file. We will discuss here what we mean by that. It won't be the case with XML snippets which have several siblings at the level 0. When enabled it denies any access to the element's parents in cases of embedding (using combinators or reference objects for instance) and sets it as the @root element.

Alternative names

root: yes | no;
sandboxed: yes | no;
sandbox: yes | no;
locked: yes | no;
lock: yes | no;
