1. when the query string contains paramaters other than C and O the colum headers seperate aditional parameters with a bare ampersand, instad of the & entity. <a href="?C=N&O=D&F=1">Name</a> 2. IMG and HR tags are not allowed in pre sections. I recomend changing the standard. 3. the title atribute to the td tag was not introduced in html 3.2. Recomend changing doc type to html 4.01 transitional.
1. yes I agree that's a bug 2. there are IndexOptions to make the output HTML3.2 compliant (which fix those issues in particular) 3. if you use the appropriate IndexOptions, the output *will* validate with validator.w3.org
I probably should clarify that point three only applies to table view.
Item 1 has been fixed in 2.1 and is proposed for backport. Item 2 ... ehm? what standard? html? agreed. ;-) As said you can use IndexOptions to fix that issues. For backwards compat we should stick with the current defaults. Item 3 doesn't appear in the current tree so I'm assuming it fixed already. I'm marking this report as fixed. Thanks for using Apache!
FYI: it's now merged into the 2.0 stable tree and will be in the next release.
