It's really simple:
<!--- create the buffer --->
<cfset doc = createObject("java", "java.lang.StringBuffer").init() />
<!--- shortcut so I don't have to type those damn chr() calls --->
<cfset crlf = "#chr(13)##chr(10)#" />
<cfset doc.append("#ownername##crlf#") />
<cfif .. >
<cfset doc.append("#attnline##crlf#") />
</cfif>
...
<!--- get the content out of the buffer --->
<cfset myDocContent = doc.toString() />
Do it this way and you can embed arbitrary logical constructs in your
code with no problem. If you don't want to use the StringBuffer (or
you can't, because you're on CF5 or less, and don't have a JVM
installed), you can do the same type of thing with string
concatenation. Just break it up wherever you need to add logic:
<cfset doc = "#ownername##crlf#" />
<cfif ...>
<cfset doc = doc & "#attnline##crlf#" />
</cfif>
....
The StringBuffer method will give you better performance to some
degree, most notably where you have either a lot of separate
concatenation operations (count the ampersands, not the CFSET tags), a
lot of content, or both.
