i feel generous today ;)

This only leads to a problem when using '_top', '_parent' or '_self'
as this results in replacing the current viewport of the browser (the
viewport the form is running in) and this surely should lead to the
destruction of the XForms processor shouldn't it? But in case i use
'_blank' (which was my original use case) i want the processor to keep
on living.  Do we possibly need to constrain the possible value space
of @target?
