Here's may take on it, for what it's worth.
A millimetre is a millimetre and a line is a line, whatever the lens and whatever the sensor.
However, lines on test targets can vary in width and contrast, often being different shades of grey ranging from black against white to a barely discernible grey against a slightly paler shade of grey. It is therefore necessary to know the MTF (or contrast) of the resolution specified, if the resolution figure is to be meaningful.
Because a line tends to alternate between black and white, it's possible to get the impression that a line is a black marking on a white background and that the space in between the black lines are not lines. For this reason one should distinguish between "line pairs" and "lines". A "line pair" consists of one dark line and the adjacent lighter line, whereas a single line can be either light or dark.
It is possible to extrapolate such a result to the full height of a sensor. Such a result is usually referred to as "Line Widths per Picture Height", or LW/PH. However, a 'line width' is a single line, not a line pair. The specification you quote of 200 lp/mm (ie. 200 line pairs/mm) is 400 line widths per mm. Therefore a 1/2.3" sensor with dimensions of 6.16x4.62mm would have a resolution of 1848 LW/PH with such a lens.
However, as I understand, such a result is an extrapolation. If you were to photograph a test chart consisting of 1848 lines, top to bottom, and fill the whole chart in the viewfinder, you wouldn't be able to count all the lines. Many of the lines, towards the top edge and bottom edge would be too blurred to discern. This is why lens test sites such as Photozone usually provided three sets of figures for LW/PH. One for the centre resolution, one for the borders, and one for the extreme edges, all at a 50% MTF contrast.
