In this post, I want to cover an item called "CustomXMLParts". Trying to look up this term you can find variations on what it is.

Unless you live under a rock, you are well aware our industry is way short on cybersecurity workers. It’s been lamented for years and shows no signs of improvement. In fact, by one account, we’re short 3.5 million workers - we’ll be no further along even five years out. So what happens when there is a massive talent gap? Let’s look at our options.
