Blackberry needs to continue to support WML, but we are using our own (legacy)
code as a plugin, so removing it from webkit is mostly fine with us. We just
use two pieces of the WML code, to deal with the different loading model
required by WML:
In FrameLoader::shouldReload:
// All WML decks are supposed to be reloaded, even within the same URL
fragment
if (frameContainsWMLContent(m_frame))
return true;
In FrameLoader::loadItem:
// All WML decks should go through the real load mechanism, not the
scroll-to-anchor code
// FIXME: Why do WML decks have this different behavior?
// Are WML decks incompatible with HTML5 pushState/replaceState which
require inter-document history navigations?
// Should this new API be disabled for WML pages, or does WML need to
update their mechanism to act like normal loads?
// If scroll-to-anchor navigations were broken for WML and required them to
have different loading behavior, then
// state object loads are certainly also broken for them.
if (frameContainsWMLContent(m_frame))
sameDocumentNavigation = false;
(And we overrode frameContainsWMLContent to detect that a frame has our plugin
loaded, rather than using the default test.)
So if these are removed we will probably need to add them back in "#if
PLATFORM(BLACKBERRY)" guards.

Subject: [webkit-dev] Dropping support for WML?
Greetings all,
We have been discussing the possibility of dropping WML support in WebKit on
IRC for a while now because
1. None of core ports (Mac, Windows, GTK, Qt, & Chromium) use it by default
2. Maintenance cost is high
I know Samsung is using the feature but they're not sure if they'll be
supporting it in the future. Are there are other folks who are actively using
WML?
Best regards.
