Merge branch 'release/2.1.5'

Fixes #30

Foreign attributes were handled incorrectly because attribute names
were implemented as pure strings without namespace prefix. This change
keeps the attributes as strings and eliminates any handling in regards
to namespaces.

Spec note about attributes:
"If designed today they would just have a name and value."
