Loose versus Strict
|
|
Changes from one doctype to another
|
|
|
|
There are changes. Wow, how insightful. Not everything changed is relevant
|
|
to HTML Purifier, though, so let's take a look:
|
|
|
|
== Major incompatibilities ==
|
|
|
|
[done] BLOCKQUOTE changes from 'flow' to 'block'
|
|
current behavior: inline inner contents should not be nuked, block-ify as necessary
|
|
[partially-done] U, S, STRIKE cut
|
|
current behavior: removed completely
|
|
projected behavior: replace with appropriate inline span + CSS
|
|
[done] ADDRESS from potpourri to Inline (removes p tags)
|
|
current behavior: block tags silently dropped
|
|
ideal behavior: replace tags with something like <br>. (not high priority)
|
|
|
|
== Things we can loosen up ==
|
|
|
|
Tags DIR, MENU, CENTER, ISINDEX, FONT, BASEFONT? allowed in loose
|
|
current behavior: transform to strict-valid forms
|
|
Attributes allowed in loose (see attribute transforms in 'dev-progress.html')
|
|
current behavior: projected to transform into strict-valid forms
|
|
|
|
== Periphery issues ==
|
|
|
|
A tag's attribute 'target' (for selecting frames) cut
|
|
current behavior: not allowed at all
|
|
projected behavior: use loose doctype if needed, needs valid values
|
|
[done] OL/LI tag's attribute 'start'/'value' (for renumbering lists) cut
|
|
current behavior: no substitute, just delete when in strict, allow in loose
|
|
Attribute 'name' deprecated in favor of 'id'
|
|
current behavior: dropped silently
|
|
projected behavior: create proper AttrTransform
|
|
[done] PRE tag allows SUB/SUP? (strict dtd comment vs syntax, loose disallows)
|
|
current behavior: disallow as usual
|
