Patrick,

you are probably right. I just expressed the thoughts behind my/our
decissions. I hope xAP will deliver what its aimed to do and it is
certainly on the way to do so. When we started the EDA project in 1999 and
moved on to VSCP xAP was just not available (at least to our knowledge).
VSCP is just a project made for fun. It is not aimed to be a world
dominator or set a standard. It is just a very simple, stupid way to make
tiny low cost little things interact with each other. It is definitly not
a threat to xAP or other "standards".

Technically speaking and in a prerfect world

test = 78;

is not harder to parse (this is what our compilers do all the time) than

<test>78</test>

Once again IMHO the XML format is much cleaner. Non of them are well
suited for microcontrollers again IMHO even if it is possible of cource.

Keep up the good work Patrick. You have really done a great work.

Regards
/Ake
