iCalendar format and usage is according to RFC 2445 and RFC 2446, with some hints taken from RFC 2447 (November 1998).

Harmgen uses ordinary least squares for harmonic analysis of tides.  An improved method that is more robust to outliers in the data is described in

Keith E. Leffler and David A. Jay, "Enhancing tidal harmonic analysis:  Robust (hybrid L1L2) solutions," Continental Shelf Research, 2008.  Available at http://web.cecs.pdx.edu/~jaylab/group/leffler/publications/Leffler_Jay_2009.pdf.

An article about a model-based approach to tide prediction, which is completely different from what XTide does, is

Derek Goring, "Computer Models Define Tide Variability," The Industrial Physicist, v. 7, n. 5, October/November 2001, pp. 14-17.

Michael Foreman's publications are a good read if you are interested in the Doodson approach to tide prediction.

Foreman, M.G.G., 1977.  Manual for Tidal Heights Analysis and Prediction.  Pacific Marine Science Report 77-10, Institute of Ocean Sciences, Patricia Bay, Sidney, B.C., 58 pp. (2004 revision).

Foreman, M.G.G., 1978.  Manual for Tidal Currents Analysis and Predition.  Pacific Marine Science Report 78-6, Institute of Ocean Sciences, Patricia Bay, Sidney, B.C., 57 pp. (2004 revision).

Foreman, M.G.G., and R.F. Henry, 1979.  Tidal Analysis Based on High and Low Water Observations.  Pacific Marine Science Report 79-15, Institute of Ocean Sciences, Patricia Bay, Sidney, B.C., 36 pp. (2004 revision).

Miscellaneous publications mentioned by Hugh Casement that I haven't read:

On the response method of tide prediction, which is completely different and allegedly better than what XTide does:  Munk, Walter H.; Cartwright, David E.:  Tidal spectroscopy and prediction.  Philosophical Transactions of the Royal Society, A 259 (1966).

An interesting-sounding publication that Hugh Casement hasn't read either:  Horn, Walter:  Some recent approaches to tidal problems (Centre Belge d'Océans, Brussels, year unknown).

Horn, Walter:  Tafeln der Astronomischen Argumente V0 und der Korrektionen j, v (Deutsches Hydrographisches Institut, Hamburg, 1967).

Doodson, in Proceedings of the Royal Society A.100 (London, 1921).

Cartwright and Tayler, in Geophysical Journal of the Royal Astronomical Society 23 (1971).
