[irrtoolset]Syntax errors in inet-rtr

Trying to reference a peering-set in an inet-rtr:

inet-rtr:   router1.example.com
descr:      AS1234 Example Company
alias:      r1.example.com
local-as:   AS1234
ifaddr:     198.32.245.52 masklen 24
peer:       BGP4 prng-example asno(PeerAS)
tech-c:     See MAINT-AS1234
mnt-by:     MAINT-AS1234
changed:    noc at example.com 20041105
source:     INTERNAL

When I submit it, I get a message back complaining of a syntax error:

UPDATE FAILED: [inet-rtr] router1.example.com
inet-rtr:   router1.example.com

#ERROR: 6: peer: Syntax error

All the material I've read indicates that this syntax should work.

Any ideas?
