string constants in simple expression language

[G.J. van de Streek]

Is there a way to use string constants in the simple expression language. I
am trying to fix a deprecation warning in:

        from("direct:saveAgentsFile")
                .setHeader(FileComponent.HEADER_FILE_NAME, "agents.xml")
               
.to("file:///Users/streekgj/Desktop/filestore/?append=false")
                ;

I tried to change it to:

                .setHeader(FileComponent.HEADER_FILE_NAME, new
SimpleExpression("agents.xml");)

Of course it is treated as an expression, but is there any way to mark it as
an string literal, or escape the dot? Something like:

                .setHeader(FileComponent.HEADER_FILE_NAME, new
SimpleExpression("'agents.xml'");)
or
                .setHeader(FileComponent.HEADER_FILE_NAME, new
SimpleExpression("agents\\.xml");)

Or do string literals only works with operations?
