cfmailparam remove attribute

The docs are here.  http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7c 15.html

It states that the default value for the remove attribute is false.  My observations that not only is that incorrect, you can't even make it false.  If I run this code,

<cfmail to="me" from="me" subject="image test" type="html">
<p>hi dan</p>
<cfmailparam file="cancel.gif" disposition="inline" remove="false">
</cfmail>

the cfmail file looks like this:

type: text/html; charset=UTF-8

server: smtp.someserver.ca:25

from: me

to: me

subject: image test

X-Mailer: ColdFusion 9 Application Server

body:

body: <p>hi dan</p>

body:

file: file:D:/DW/dwtest/Dan/cancel.gif

file-disposition: inline

remove: true

Does this happen to anyone else?
