14164	Automatic localization of numbers (L10N) in templates can cause invalid sitemap priorities	Mathijs de Bruin	nobody	"When specifying priorities for a sitemap as a float (as is suggested by the official documentation) and `USE_L10N = True`, it can happen that requested sitemaps contain comma's in the priority values for items when the server detects certain locales. As the sitemaps specification requires a dot as a separator for float values this yields an invalid sitemap and has been confirmed to prohibit the indexing of certain sites.

The problem can be reproduced as follows:
 1.  Make sure `USE_L10N = True` in `settings.py`.
 2.  Create a Sitemap object with a priority and expose it somewhere in the URL space. (For example: `priority = 0.5`)
 3.  Request the sitemap with a browser for which the decimal separator is something other than a dot. (This holds for many European locales.)
 4.  Priority value should now be rendered wrongly. (For example: `<priority>0,5</priority>`)

As this problem is likely to occur for other situations where templates are used to render machine-parseable content, a structural solution should be in order. "		closed	Internationalization	1.2		fixed	internationalization L10N sitemaps comma		Unreviewed	1	0	0	1	0	0
