I have noticed that some composers, no doubt eager to comply with the current requirements, are preserving final full-stops when phrases are repeated, e.g:
Hosanna in the highest. Hosanna in the highest.
rather than the more usual and arguably more correct:
Hosanna in the highest, Hosanna in the highest.

There is no 'approved style' for the punctuation of the repetition of text.
We would expect it to make sense and be consistent. The one other relevant
comment was that in a responsorial setting either it should be punctuated as
two separate texts or one continuous text - but not a mixture.
There would not be a problem with your first example with the full stop. In
the second I would only query the capital H on the second Hosanna. The
Missal text does not follow poetic capitalisation nor do I think that here
it is a word which is marked as a title or theologically significant (e.g
Death, Resurrection).
Yet this is contrary to standard English usage and principles of type-setting and publishing.
Elaine Gould, Behind Bars, Faber Music Ltd, 2011, page 438:
"Use upper- and lower-case letters (never exclusively capitals) exactly as
written by the author, including poetic capitalization after line breaks in
the text. Punctuation follows the author's original, even where this is
contrary to the musical phrasing.
Where a word, phrase, or line of text is to be repeated, commas separate the
repetitions and the final punctuation comes only at the very end."
Confused? I am.
