Nice idea !  But I've got a suggestion to do : Define every Nodes as they
appear.  A part with just one Node equals a I/O Connection.  This way you
can create Voltage / Input / Output / etc.  Nodes at will ...  And put the
"Value" parameter at the second position (The number of nodes can vary ...)
Example :

V++   12v       1         'Define a first voltage
GND   0v        2         'Define Ground
VCC   5v        3         'Define a second voltage
Clock 2Khz    4   'Define I/O
Out0  Trigger  5          'Define I/O

And than go on with whatever parts you want to connect.  This way _all_ of
the connections (Nodes, names & values) are defined in the file ...

By the way : It's not mandatory this way to define the I/O at the beginning
of the file, they can be defined anywhere.

It will probably not be possible to read this kind of file into a CAD
package, but it _is_ possible to recognise ( at first glance ! ) all
connections that are made, enabeling everyone to write their own
"conversion" routines for their favorite schematic packages.
