cherrypick from mnc-dev docs: Fixed typos in XML snippet
Original Change-Id: I9d364a6649aa0eef7453d26a880aee7a17ddbfbf

The XML code snippet had two malformed tags; fixed.
See first comment for doc stage location.

Mistakenly created this fix in the wrong branch and got my +1s
there. After we merge it here on mnc-ub-dev, I'll cherrypick it
*again* to mnc-docs so we can update developer.android.com with this
fix.
