[crossfire] File format

[Nathaniel Kipps]

A few points, hopefully helpful, maybe flaming:

> SGML

Since XML is a subset (superset?) of SGML, I think finding and
incorporating an XML parser is much easier than a SGML one.

> YAML

I hate the idea of being whitespace dependent. Although, I haven't
actually *used* YAML...

I think the biggest tug of war would be between JSON and XML. I would
likely lean toward JSON, since it's more compact.

I think it's important that editing tools are more or less ironclad
before making a big change. As hard as it is to learn to make and
submit new/changed content, I'd hate to see it get more intimidating
through adoption of new formats.

Overall, I'll be sad to see a departure from the current flat files,
though I acknowledge that the need for something more "standard" is
legitimate.
