>>TITLE MapSubwindows XPROTO
>>ASSERTION A MapSubwindows-1
When a client sends a valid MapSubwindows protocol request
to the X server, and the parent window is not mapped, and
the client has no event selected in the event_mask for any
window, then the X server does not send back an error, event
or reply to the client.
>>STRATEGY
Call library function testfunc() to do the following:
Open a connection to the X server using native byte sex.
Send a valid MapSubwindows protocol request to the X server.
Verify that the X server does not send back an error, event or reply.
Open a connection to the X server using reversed byte sex.
Send a valid MapSubwindows protocol request to the X server.
Verify that the X server does not send back an error, event or reply.
>>ASSERTION A MapSubwindows-2
When a client sends an invalid MapSubwindows protocol
request to the X server, in which the length field of the
request is not the minimum length required to contain the
request, then the X server sends back a BadLength error to
the client.
>>STRATEGY
Call library function testfunc() to do the following:
Open a connection to the X server using native byte sex.
Send an invalid MapSubwindows protocol request to the X server with length 
  one less than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.
Open a connection to the X server using reversed byte sex.
Send an invalid MapSubwindows protocol request to the X server with length 
  one less than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.

Open a connection to the X server using native byte sex.
Send an invalid MapSubwindows protocol request to the X server with length 
  one greater than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.
Open a connection to the X server using reversed byte sex.
Send an invalid MapSubwindows protocol request to the X server with length 
  one greater than the minimum length required to contain the request.
Verify that the X server sends back a BadLength error.
>>ASSERTION B MapSubwindows-3
When a client sends an invalid MapSubwindows protocol
request to the X server, in which the length field of the
request exceeds the maximum length accepted by the X server,
then the X server sends back a BadLength error to the
client.
>>STRATEGY
Call library function testfunc() to do the following:
Open a connection to the X server using native byte sex.
Send an invalid MapSubwindows protocol request to the X server with length 
  one greater than the maximum length accepted by the server.
Verify that the X server sends back a BadLength error.
Open a connection to the X server using reversed byte sex.
Send an invalid MapSubwindows protocol request to the X server with length 
  one greater than the maximum length accepted by the server.
Verify that the X server sends back a BadLength error.
