I am updating my sitemap on daily basis with the latest status of my stock. The level of priority is different. The products which are in my stock having priority 1 and the products which are out of stock in my e-commerce website i am not removing them from my sitemap and giving them priority as 0.3

Is it right what i am doing or do i need to remove the out of stock products from my sitemap?
