Rudimentary support inclusion of xml files using <include/>
Rudimentary support inclusion of xml files using <include/>

We need some custom attributes here, so make our own <include/> tag rather
then implementing XInclude machinery

Attributes:
  * 'file' - what to include; path to be relative to layout directory

  * 'auto-locale': yes|no, default yes -- when 'yes', locale specific version
    of the include is loaded, same as is done for layouts themselves.
