how does they affect in site map

[phparion]

hi

i am generating XML site map for my site to post in google..

after study i found two confusing tags

<priority>0.5</priority>
<changefreq>daily</changefreq>

different people use different values in these tags,

i want to ask what is the best value for these tags and how does it affect my page ranks in google? in fact currently my site has PR 5 and i dont want to lose it by any mistake.

therefore i want to double check this issue before i post my sitemap in google..

please reply..

thanks

Please note that the priority you assign to a page has no influence on the position of your URLs in a search engine's result pages.
