Does SOAP spec allow non-xml content between headers and envelope

[gailfuzzy]

Is the following allowed according to the SOAP spec?\[code\]HTTP/1.1 200 OKContent-Type: text/xml; charset="utf-8"000 OK.<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/> <SOAP-ENV:Body> <m:GetLastTradePriceResponse xmlns:m="Some-URI"> <Price>34.5</Price> </m:GetLastTradePriceResponse> </SOAP-ENV:Body></SOAP-ENV:Envelope>\[/code\]Note the "000 OK." I can't find anything about it in the official spec: http://www.w3.org/TR/2000/NOTE-SOAP-20000508/
