is set to 0, these changes apply only to the current drawing session.
They are discarded when you end the drawing session, or when you reload
or detach the xref.
You can also control
the fade display of the DWG xref. The XDWGFADECTL system variable
defines the fade percentage for all DWG xrefs.

boundary, you can turn on the XCLIPFRAME system variable.
