      Description

      Whatever the input HTML meta are, tika's HTML meta can only have a "name" and a "content" attribute. This gives invalid HTML meta tags for in the output.

      For instance, the following valid HTML file

      <!DOCTYPE html>
      <html lang="en">
        <head>
          <title>Title</title>
          <meta http-equiv="refresh" content="0; url=http://example.com">
        </head>
        <body></body>
      </html>
      

      is transformed into a SAX stream corresponding to the following HTML :

      <html xmlns="http://www.w3.org/1999/xhtml">
      <head>
      <meta name="dc:title" content="Title"/>
      <meta name="Content-Encoding" content="ISO-8859-1"/>
      <meta name="refresh" content="0; url=http://example.com"/>
      <meta name="Content-Type" content="text/html; charset=ISO-8859-1"/>
      <title>Title</title>
      </head>
      <body/></html>
      

      (the redirection, content-type, and content-encoding are all specified in a non-standard way)

      The information that the original file had an "http-equiv" meta tag is lost, and replaced by a generic "meta name=" tag.

      This is annoying when working with classes expecting valid meta redirection, such as Nutch's HTMLMetaProcessor, for instance.
