That's a static method. Is it OK to have static methods in IDL? If so
would it make sense to add the following to IAText2?
=====
HRESULT IAccessibleText2::offsetInParent (
[in] IUnknown* accessible,
[out] long* offset
);
Return the text offset in the parent of the specified accessible.
Return the text offset in the parent of the specified accessible
corresponding to the beginning of the text associated with the specified
accessible.
Returns:
S_OK is returned if the parent accessible implements IAccessibleText.
S_FALSE is returned if the parent accessible does not implement
IAccessibleText; [out] value is -1.
Note: This is a static method.
=====
Also, what interfaces are implemented on the child nodes?
BTW, not being in the situation of needing this for my own
implementation I'm trusting our implementers to convey whether or not
this is generally useful to the IA2 community. If not then we shouldn't
add the method especially since there is the solution of the private
interface.

We do have a precedent in IADocument::anchorText. That's the only
method in that interface.
