248 \param data is a string representation of the Inset contents.
249 It is often little more than the output from Inset::write.
250 It is passed to, and parsed by, the frontend dialog.
251 Several of these dialogs do not need any data,

253 \param inset ownership is _not_ passed to the frontend dialog.
254 It is stored internally and used by the kernel to ascertain
255 what to do with the FuncRequest dispatched from the frontend
256 dialog on 'Apply'; should it be used to create a new inset at
257 the current cursor position or modify an existing, 'open' inset?
