exactly.

yes. Only change: page["thing"] = "Something".

would be possible, too, but maybe with this special syntax:

page.10 = Text
page.10.value = "Hello"
page."thing" = Text
page."thing".value = "Suggestion"

So the rule in EBNF for a part of the object path would be:

ObjectPath = [ "." ] ObjectIdentifier { "." ObjectIdentifier }  
( [ "." VariableName ] | [ ArrayOffset ] );
VariableName = "$" Identifier;
ArrayOffset = Number | Literal
Literal = DoubleQuotedLiteral | SingleQuotedLiteral;

Well, that would be an option.
