"Dotted namespace" how's that?
shouldn't be rather be "Dotted unit names" and "namespaces"?
Since "dotted name" actually specify "namespace".
And a name of a space (scope), shouldn't have any dots  since dot is a
separator.

Because "dotted unit names" (without actual namespaces) might break
compatibility with delphi's namespaces.

See:
http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/devcommon/usingnamespaces_xml.html

For example: section "Multi-unit Namespaces"
unit MyCompany.ProjectX.ProgramY.Unit1
unit MyCompany.ProjectX.ProgramY.Unit2

"In this example, the namespace MyCompany.ProjectX.ProgramY logically
contains all of the *interface* symbols from unit1.pas and unit2.pas.

Symbol names in a namespace must be unique, across all units in the
namespace. In the example above, it is an error for Unit1 and Unit2 to both
define a global interface symbol named mySymbol. "
thanks,
Dmitry
