How the scope of the loaded variables are treated,
|
|
which must be one of local, parent or global. local
|
|
means variables are loaded into the local template
|
|
context. parent means variables are loaded into both
|
|
the local context and the parent template that called
|
|
it. global means variables are available to all
|
|
templates.

Whether or not variables are visible to the parent
|
|
template, same as scope=parent. NOTE: This attribute is
|
|
deprecated by the scope attribute, but still supported.
|
|
If scope is supplied, this value is ignored.
