Farrukh,
I must confess svn is my go-to solution - and I cannot live without tortoisesvn client for Windows - using it daily.
Is there a similar solution for Mercurial or git VCS? If there's something better - I'm definitely interested in looking into it! I'm familiar with some svn limitations.
You are indeed correct that it had escaped my attention that OASIS now has svn - and most definitely this is something now as a priority to facilitate specification work - so I will look into this soonest.
Thanks, DW
