LGTM - a couple of style choices, but just want to make sure that the nested snippets aren't shown in the outer snippet when extracted to the docs

[twsouthwick]

How does this look for snippet 4? does it remove the Snippet5 comment?

[mikeebowen]

Yes, the tags remove all other tags as well as themselves. That's why the last sample showing the complete code has to be in a surrounding all the code, if you just point the sample at the whole file then the comments showing the tags are not removed.

[twsouthwick]

in the future, it will be helpful to have the title include the sample it's reworking
