The package name form help is not strict enough

[Alejandro J. Cura]

When submitting a new application, this text is displayed below the package name field:
"The package name for this application. Letters, numbers or hyphens allowed only."
But the package name also needs to match the one in the app manifest, or else the apps will not be started.

So until this check is automated, the help text should include some bold red & blinking warning text like:
"Make sure this matches the last part of the "name" field on the app manifest."

The namespace should match too, but I don't know where to request it other than on the page that the reviewers get.
