Include directive processing in the browser
This document describes how the include directive is processed in the browser environment (xmlhttprequest IO module). This handling has slightly different rules than when a file-based document. The rules are listed in the order in which they are applied.
In these definitions, there are several commonly occurring terms that pertain to the include directive:
target - the target of the include directive as specified in the document
include path - the resolved path of the include; usually an absolute path or URL
