The Internet has developed two major breeds of protocol formats.
The binary ones are extremely efficient but usually not very flexible
while the plain-text ones are reaching out for achieving perfection
in data representation while leaving the path of efficiency. Some
protocols such as HTTP and SIP are in-between these two schools,
offering both a text-based extensible syntax (it's actually easier to
add a header to HTTP than to come up with a namespace for XMPP...)
and the ability to deliver binary data. But these protocols do not
come with native data structure support. PSYC is a protocol that
combines the compactness and efficiency of binary protocols with the
extensibility of text-based protocols and still provides for enough
data structuring to rarely require the use of other data formats.
