I want to know the answer to the following question:
What is the basis of capitalization standards for the sentence-style capitalization?
All the background I'm provided with is that "The convention followed by many British publishers (including scientific publishers, like Nature, magazines, like The Economist and New Scientist, and newspapers, like The Guardian and The Times) and U.S. newspapers is to use sentence-style capitalisation in headlines, where capitalisation follows the same rules that apply for sentences.". Is that enough to answer the question?
Answer: yes
