| // |
| // - arguments which are nodes become children |
| // - arguments which are strings become text node children |
| // - arguments which are objects have the object's properties added as: |
| // - attributes if the property name does not begin with "$" |
| // - properties if the property name begins with "$" |
| // (the resulting property name doesn't include "$") |
