In the XML example on this page, the whitespace had been stripped out, so there were no spaces between adjacent attribute values or keys.
This made it hard to read, though the original formatting allowed for a scroll bar, so the text was not running into the side of the page (compare to https://github.com/MicrosoftDocs/windows-itpro-docs/pull/3847 and https://github.com/MicrosoftDocs/windows-itpro-docs/pull/3850, where the uncorrected formatting forced the text to run into the side menu).
