Is use of \s5 valid?

[kavitharaju]

Several of the UsfmjsTests in the repo contain the use of \s5 marker? Is it a valid USFM marker? If yes, shouldn't it contain some text in it like other \s# markers?

Only \s1 - \s4 are defined in the grammar. The current documentation site doesn't explicitly note that there is a limited number of markers.

I believe for syntax that empty paragraphs should be accepted. In Paratext, users would need to run a check to see that they have empty paragraphs or empty character markers.
