            Bug ID: 25526
           Summary: Invalid IDL fragment in 4.10.20 - APIs for text field
                    selections
           Product: HTML WG
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HTML5 spec
          Assignee: dave.null@w3.org

The first fragment of IDL defined in 4.10.20 is invalid as a standalone IDL
fragment. In particular, it cannot be extracted and inserted into an IDL file
without producing a syntax error. All other IDL fragments in the spec do not
have this problem. This presents a problem for tools that harvest IDL from the
HTML spec in order to construct a valid IDL file corresponding to the IDL
entities defined in the spec. Further, at present, the current definition is
semantically incomplete from the IDL perspective since it fails to bind the two
affected interfaces with the members defined by this fragment.

In order to correct, I would suggest wrapping these methods in a new
[NoInterfaceObject] interface definition which is then used in "implements"
statements for the HTML{Input,TextArea}Element interfaces. 

For example, add the wrapper:

interface TextSelection {
  ...
};
HTMLInputElement implements TextSelection;
HTMLTextAreaElement implements TextSelection;

where ... is the current incomplete fragment:

  void select();
           attribute unsigned long selectionStart;
           attribute unsigned long selectionEnd;
           attribute DOMString selectionDirection;
  void setRangeText(DOMString replacement);
  void setRangeText(DOMString replacement, unsigned long start, unsigned long
end, optional SelectionMode selectionMode = "preserve");
  void setSelectionRange(unsigned long start, unsigned long end, optional
DOMString direction = "preserve");

Note that this problem also holds with HTML5.1 nightly.
