Currently it's being done by adding lines like following into 
modules which contain widgets to publish:

import dlangui.widgets.metadata;
mixin(registerWidgets!(Widget, TextWidget, ScrollBar, 
CanvasWidget)());

Unless widgets are registered, it's impossible to create them 
from DML like this:

auto layout = parseDML!VerticalLayout(q{
     VerticalLayout {
         layoutWidth: fill; layoutHeight: fill; backgroundColor: 
#FF8080
         TextWidget { text: "Input text here" }
         EditLine { id: edName  }
     }
});

Sample DML editor:
     dub run dlangui:dmledit
