[Mapcss] ::subpart syntax

[Thomas Davie]

OpenStreetPad's grammar for this specifies:

Selector        ::= <Subselector>+ <LayerIdentifier>?;
LayerIdentifier ::= '::' 'Identifier';
Subselector     ::= <Object> 'Whitespace' | <Object> <Zoom> <Test>* | <Object> <Test>* | <Object> 'Whitespace' <Class>;"

i.e. layer identifiers come at the end of selectors, not at the end of sub selectors, so indeed, your latter example would not parse.
