Quote:

Attribute Description
<urlset> required

Encapsulates the file and references the current protocol standard.
<url> required

Parent tag for each URL entry. The remaining tags are children of this tag.
<loc> required

URL of the page. This URL must begin with the protocol (such as http) and end with a trailing slash, if your web server requires it. This value must be less than 2,048 characters.
<lastmod> optional

The date of last modification of the file. This date should be in W3C Datetime format. This format allows you to omit the time portion, if desired, and use YYYY-MM-DD.

Note that this tag is separate from the If-Modified-Since (304) header the server can return, and search engines may use the information from both sources differently.
<changefreq> optional

How frequently the page is likely to change. This value provides general information to search engines and may not correlate exactly to how often they crawl the page. Valid values are:

* always
* hourly
* daily
* weekly
* monthly
* yearly
* never

The value "always" should be used to describe documents that change each time they are accessed. The value "never" should be used to describe archived URLs.

Please note that the value of this tag is considered a hint and not a command. Even though search engine crawlers may consider this information when making decisions, they may crawl pages marked "hourly" less frequently than that, and they may crawl pages marked "yearly" more frequently than that. Crawlers may periodically crawl pages marked "never" so that they can handle unexpected changes to those pages.
<priority> optional

The priority of this URL relative to other URLs on your site. Valid values range from 0.0 to 1.0. This value does not affect how your pages are compared to pages on other sites—it only lets the search engines know which pages you deem most important for the crawlers.

The default priority of a page is 0.5.

Please note that the priority you assign to a page is not likely to influence the position of your URLs in a search engine's result pages. Search engines may use this information when selecting between URLs on the same site, so you can use this tag to increase the likelihood that your most important pages are present in a search index.

Also, please note that assigning a high priority to all of the URLs on your site is not likely to help you. Since the priority is relative, it is only used to select between URLs on your site.

Been using sitemaps for a few months now and seems to me that either I'm submitting something incorrect or Google ignores URLs that are submitted to it and goes off and does the URL it finds.
Does anyone else have this experience?

Can anyone explain there understanding for parameters lastmod, changefreq and priority.

Especially the prioirity. Is a high priority 1 and a low priority 0, with increments like of 0.75 and 0.8 allowed? I thought so from the above info. But experience of googlebot visiting doesn't fit that thinking.
I have a small proportion(about 2%) of 0.75 prioirty a few(0.5%) set at 1 prioirity. But those URLS are ignored constantly.
Anybody else care to share experieinces on this?

As I have experienced the priority is only a suggestion for google. I shows your rate about the importance of each pages in your site structure, the desired visiting rate. I got some error message when the submitted sitmap contained urls, that don't fit to the preferred domain.
