[TYPO3] Change page title only to one page

[Cray Flatline]

I'm rewriting page titles with such script

config.noPageTitle = 1
page.headerData.1 = TEXT
page.headerData.1 {
    field = title
    noTrimWrap = |<title>|, additional text </title>|
}


But I need to rewrite title ONLY of root page (id=1) to "Root title
text". Can somebody help me with it? I tried to make it with "if {}" in
above script but it didn't work. I'm a newbie in TS, so please help me. 
  :-)

(sorry for above mail - some troubles with mailer)
