I don't pretend this is a big deal, but I notice it and it interrupts my reading flow so I thought I'd point it out. The possesive form of "its" - that is, when the word is used to mean, "belonging to it," does not take an apostrophe. The only time it is appropriate to include an apostrophe in the word "its" is when the word is a contraction of "it is". I would be happier with the document if its usage of the word were correct. Thank you.
