Does package name support is, for...

I notice that when you put in your Project -> Package Name word "is" or "for" the compiler return error because of that word.

Is that B4A problem or is android rule that package name can't contain that words

For example I want to name my package project:

my.app.for.android or
my.app.is.android

A package name cannot include any java reserved keyword. It is a java restriction.

I was thinking that is something like that.
Thanks Erel
