dovecot - Sep 2011 - Sieve "header :value" test does not work

hi,

After following some examples and searching for sieve samples in this ml
history, I'm quite sure that the following sieve snippet should give no
surprises:

if header :value "ge" :comparator "i;ascii-numeric"
"X-Header-Name"
"0.99" { /* do something */ }

However the Pigeonhole Sieve 0.2.3 on dovecot 2.0.14 gives me following
error:

test: line 3: error: unknown tagged argument ':value' for the header
test (reported only once at first occurence).
test: error: validation failed.

What obvious mistake am I failing to see here?

To answer my own question (which was found by grepping through
/usr/share/doc/dovecot-2.0.14/sieve/rfc/*bz2): including the
"relational" extension in the "require" statement adds
support for this
test.

Sorry for the noise :/
