non-normative best practices & file caching

The WOFF WD has two appendices that describe best practices:

  http://www.w3.org/TR/2010/WD-WOFF-20100727/#appendix-b
  http://www.w3.org/TR/2010/WD-WOFF-20100727/#appendix-c

These were discussed in a June telcon:

  ACTION: jonathan to create non-normative best practices appendix

  http://www.w3.org/2010/06/02-webfonts-minutes.html

The appendices are not labelled as non-normative in the WD, I suggest
we add this text to each of them:

  This appendix is informative, not normative.

Like here:

  http://www.w3.org/TR/CSS2/sample.html

Further, I suggest one change to appendix C:

  The WOFF-packaged data will typically be decoded to its original
  sfnt format for use by existing font-rendering APIs that expect
  OpenType font data, but such a decoded font should not be exposed as
  a file on disk, and must not be installed "globally" for use by
  other processes or documents on the system.

should be:

  The WOFF-packaged data will typically be decoded to its original
  sfnt format for use by existing font-rendering APIs that expect
  OpenType font data. It is acceptable for clients to store decoded
  files in a cache, but decoded files should not be installed for use
  by other processes or documents on the system.

I.e., I think it's ok for browsers to cache decoded files, but they
shouldn't be exposed in other ways.
