A question about Content-Length header

Dear Sirs,

As I understand, Content-Length header is not mandatory with HTTP 1.1.

My question is: when a HTTP message has message body (eg. a SOAP envelope)
but does not send Content-Length header,is it a MUST (semantics as by RFC
2119) for the message body to be "chunked" transfer-coded as defined in Sec
3.6.1 of RFC 2616 or be transfer-coded in other scheme?

Thanks & Regards,
