Discussion
Using this function is the easiest and most efficient way to create a paragraph style. Paragraph styles should be kept immutable for totally lock-free operation. If an invalid paragraph style setting specifier is passed into the settings parameter, nothing bad will happen, but you will be unable to query for this value. The reason is to allow backward compatibility with style setting specifiers that may be introduced in future versions.
