dhtmlLayout innerHTML

It would be nice to add new function dhtmlLayout innerHTML, because now I need to create some work around to set layout html content from ajax response.
As I see in some features it`s already done:
tabbar.setContentHTML(“a1”,htmlcontent);

layout has the attachHTMLString method (but we didn’t add the information about it in the documentation by mistake).

layout.cells(cellId).attachHTMLString(str);

Moreover there attachURL(url,true) method that loads the content by Ajax:

layout.cells(cellId).attachURL(url,true);
