Re: Protocol questions

[Mal Lansell <mal@xxxxxxxxxxx>]

I've some protocol questions of my own:

1) When driving MediaPortal with media.basic messages, I've been sending
URLs in the message, including '/' or '\' characters - are those
actually permitted?

2) What is the reason for the 128 char limit on the length of the value
in a name=value pair?  It means I have to split my URLs onto multiple
lines (not such a biggy, I was just curious really)

3) Should we have a method for giving "official" status to
schemas?  I'm
thinking of the media.basic schema again.  Tony introduced it, but with
him not contributing to xPL any longer (in fact, his MyHap protocol has
the look of another xAP/xPL style split), it doesn't seem right for him
to have ownership of that schema anymore.  I'm using it with my
MediaPortal plugin, and I would prefer to develop it as I see fit
without reference to someone who no longer contributes...
