To put a little bit more gas into this fire, some stats on current "brokeness" of OpenACS w.r.t. web standards:
- Total number of .ADP files: 1171
- Number of .ADP files with unquoted attributes: 951 (that is 90%!)
- Number of pages with <br> or <hr> instead of <br /> or <hr />: 547/739 respectively
- Number of pages that use FONT tag: 243
- Number of pages, where <p[ >] and </p> counts are different (P is likely to be left open): 356
- The same for LI: 140
These counts may not be too accurate, but I am sure they are pretty close.
