It is a seperate piece which could be pryed off too. The door frame is supposed to be independently shimmed and nailed which would allow the prying and re-installing a piece of brick mould. This option may even be the easier method of repair. Let us know how it turns out, send pictures.
The way things are all one piece these days I was afraid the way it looked it was not but I will check it closer. The only problem with the replacement is having to be delicate with the siding so close by but the other could be a problem getting the plastic wood to match the shape. At least you confirmed my two options.
Thanks for the help and for the forum I have enjoyed all the tips.
