I hope the ID name doesn't collide with other IDs. Google search didn't give me any exact matches.
Also, to my surprise, mw-content-ltr shows up as a google search suggestion, which means a lot of people wondered what it is :-S
A lot of people on en.wikisource were wondering how to use the ms-content-ltr container to replace an interim container scheme used for dynamic layouts of transcluded content once it went through the ProofReading process. This additional ID generated skin-wide would greatly help cut down on the amount of local .js currently needed (not to mention help stop abusing #contentSub where the interim container is being dynamically moved to).
Any chance this revision slated for 1.20wmf with the new ID attribute generation could be hurried along? Patching the current wikisource deployed version sooner rather than later sure could go a long way in undoing our dynamic layout mess moving forward. TIA - GOIII
I'm tagging this with 1.19wmf1 so if possible/allowed it will be deployed to WMF wikis.
Should this go into 1.19 aswell?
I see you did so already.. that's even better I suppose :)
