Empty attributes in form tags

Hi all,

I'm looking for a simple way to switch input fields from
readwrite to readonly. The readonly attribute for <input ...> tags
is an attribute without value. 

The following code does not work:

--- schnipp ---
[[\
computername = "mycomp"
if ( mySwitch ):
	ro="readonly"
else:
	ro=""
]]

<f:text name="cname" value="=computername" ="=ro" />
--- schnapp ---

If mySwitch is True this should render to:

<input type="text" name="cname" value="mycomp" readonly />

if mySwitch is False this should render to:

<input type="text" name="cname" value="mycomp" />

How can I insert valueless attributes in form tags without using
if, elif, else? Is it possible?

Regards Konrad
