I am not sure what you mean but XWD based on the MSCI World Index is a market cap weighted global equity ETF, the single largest holding that both my ex and myself have. We bought it when it first made its presence and have huge unrealized cap gains. I don't like it due to its MER and would prefer, with the newer ETFs today, to have XAW and a separate Cdn equity allocation such as XIC just because of MER.
The iShares MSCI World Index ETF seeks to provide long-term capital growth by replicating, to the extent possible, the performance of the MSCI World Index, net of expenses. The MSCI World Index is a free float-adjusted market capitalization weighted index provided by MSCI, Inc. that is designed...

What I mean is answered here:
Why XWD?
1. Exposure to large and mid-cap equities from developed markets countries around the world
There's no exposure to small cap and no exposure to EM. Look at the exposure breakdown. No China. No South Korea. No Taiwan. No India. No Brazil. And so on.
When FTSE (Vanguard) say Global, it's everything. When MSCI (BlackRock iShares) say World, it's the developed market. The equivalent to FTSE's Global is MSCI's ACWI, not MSCI's World.
I would certainly like to have exposure to something like China's BABA for instance which is present in NYSE's VT and ACWI, in TSX's XAW and VXC, but not in XWD and interestingly ZGQ Quality factor didn't pick on BABA.
XWD isn't bad, it performed awesomely good, obviously because it's highly diversified. Pretty similar to XAW performance actually, which is interesting, but one should know that it doesn't have EM exposure and it doesn't have small cap exposure, so it's not truly a "everything-ETF". I mean here that it could be even more complete in its diversification, and that's FTSE Global or MSCI ACWI.
