that's not the preferred format for writing XML, this is:

    <?xml version="1.0" encoding="UTF-8"?>
    <claims>
      <claims_I_did_not_make description='Claims that I did not make or defend.'>
        <claim>Patch is perfect.</claim>
        <claim>Ambiguity is good.</claim>
        <claim>There are no better formats for conveying patches.</claim>
      </claims_I_did_not_make>
      <claims_I_did_make description='What I actually said.'>
        <claim>Patch files are readable by humans.</claim>
        <claim>Being readble by humans is useful.</claim>
        <claim>XML is painful for humans to read and write.</claim>
        <claim>JSON is painful for humans to read and write.</claim>
        <claim caveat='Actually this would require all parties to handle JSON or XML correctly which on further reflection I am not sure about. Still, it is a claim I initially made.'>JSON or XML would actually fix this problem in the format.</claim>
      </claims_I_did_make>
      <claims_I_did_not_make_but_am_open_to description='Things that were never specified but that I do not actually disagree with.'>
        <claim>The patch format could be improved.</claim>
        <claim>Formats should be unambiguous.</claim>
        <claim>Separating sections is good.</claim>
      </claims_I_did_not_make_but_am_open_to>
    </claims>

That's really not that bad, especially with indentation and color coding. You're kind of cheating by putting it into HN, which is terrible for code.

> XML is painful for humans to read and write.

Speaking of claims no-one made; no-one's talking about writing patch files by hand.
