Blogger breaks my HTML.

My template is well-formed, and valid XHTML.

The source of my blog entries is well-formed and valid XHTML.

The output of my entry inserted into the template is broken XHTML.

Somewhere along the line, BloggerTripod converts my opening and closing body tags into BODY tags, </b> tags into </B> tags and my <blockquote> tags into <Blockquote> tags, which means my page is no longer valid (since it leaves the case of the opening tags alone, giving me a million and one “invalid nesting” errors), which, pretty obviously, I’d really like it to be.
