Try wrapping the entire thing in a cfsavecontent tag and then trim the output:
<CFSAVECONTENT VARIABLE="XMLOUTPUT">
<CFPROCESSINGDIRECTIVE SUPPRESSWHITESPACE="Yes"><CFSETTING
ENABLECFOUTPUTONLY="Yes" SHOWDEBUGOUTPUT="No">
<CFIF NOT ISDEFINED("do")>
<CFOUTPUT>
<html><body><form></form></body></html>
</CFOUTPUT>
<CFELSEIF do EQ "xml"><CFOUTPUT><?xml version="1.0"?>
<!DOCTYPE Foo SYSTEM "http://www.foo.com/bar.dtd";>
<Foo></Foo>
</CFOUTPUT>
</CFIF>
<CFSETTING ENABLECFOUTPUTONLY="No"></CFPROCESSINGDIRECTIVE>
</<CFSAVECONTENT>
<CFOUTPUT>
#TRIM(XMLOUTPUT#
</CFOUTPUT>
