Some time ago an astronomical committee degraded PLUTO from a true planet into a simple Kuiper belt object, a dwarf planet.
From its discovery in 1930 until 2006, Pluto was counted as the Solar System's ninth planet. In the late 20th and early 21st centuries, however, many objects similar to Pluto were discovered in the outer solar system, notably the scattered disc object Eris, which is 27% more massive than Pluto
New knowledge ermerged that changed the common interpretation of what was a planet or not. An international institution, the IAU made a decision:
On August 24, 2006 the IAU defined the term "planet" for the first time. This definition excluded Pluto, which the IAU reclassified as a member of the new category of dwarf planets along with Eris and Ceres. After the reclassification, Pluto was added to the list of minor planets and given the number 134340.
Now, how does it relate to OOXML? The problem underlying the decision is that the IAU decided to break backwards compatibility with millions of school books, astronomical literature, sky maps, planetarium equipment, and our common knowledge. For sure, Pluto stays the planet of our hearts.
The discovery of Pluto was rooted in a misconception. When analyzing the orbits of the planets, scientists found that the orbit of Uranus didn't match their calculations. This discrepancy was thought to be the result of gravitational interactions with a more distant planet. However, Pluto is not massive enough to affect the orbits of the planets, and the discrepancy eventually turned out to have been caused by an overestimation of the mass of Neptune.
Natural science works like this, ideally by falsification. This was not always the case. Galileo Galilei's teaching for instance broke backwards compatibility with an existing corpus of religious documents.
In 1610 Galileo published an account of his telescopic observations of the moons of Jupiter, using this observation to argue in favor of the sun-centered, Copernican theory of the universe against the dominant earth-centered Ptolemaic and Aristotelian theories. The next year Galileo visited Rome in order to demonstrate his telescope to the influential philosophers and mathematicians of the Jesuit Collegio Romano, and to let them see with their own eyes the reality of the four moons of Jupiter. … In 1612, opposition arose to the Sun-centered solar system which Galileo supported. In 1614, from the pulpit of Santa Maria Novella, Father Tommaso Caccini (1574–1648) denounced Galileo's opinions on the motion of the Earth, judging them dangerous and close to heresy. Galileo went to Rome to defend himself against these accusations, but, in 1616, Cardinal Roberto Bellarmino personally handed Galileo an admonition enjoining him neither to advocate nor teach Copernican astronomy.
This move of the church authorities was completely misunderstood. In fact, the backwards compatibility with the existing corpus of documents and a shortage in writer supply and ink made it more practical to slow the migration process down.
Western Christian biblical references Psalm 93:1, Psalm 96:10, and 1 Chronicles 16:30 include text stating that "the world is firmly established, it cannot be moved." In the same tradition, Psalm 104:5 says, "[the LORD] set the earth on its foundations; it can never be moved." Further, Ecclesiastes 1:5 states that "And the sun rises and sets and returns to its place, etc."
A slow migration process is always to be preferred to ensure a streamlining with the existing corpus of documents:
On February 15th, 1990, in a speech delivered at the Sapienza University of Rome, Cardinal Ratzinger cited some current views on the Galileo affair as forming what he called "a symptomatic case that permits us to see how deep the self-doubt of the modern age, of science and technology goes today." .. On 31 October 1992, Pope John Paul II expressed regret for how the Galileo affair was handled, and officially conceded that the Earth was not stationary, as the result of a study conducted by the Pontifical Council for Culture.
