Was the writing system used in the Empire of Japan (大日本帝国) called 真片仮名?


So, today I encountered the claim on
[Wikipedia](https://en.wikipedia.org/wiki/Kana)

> Shinkatakana (真片仮名, mana and katakana): mixed script including only kanji
> and katakana.

Wikipedia doesn't list a source for this claim.  
This sounds to me like the writing system used by the 大日本帝国 (and I'm sure in
many other contexts) with 漢字 and the 送り仮名 written in small 片仮名. But googling
about 真片仮名 gives me no good results, or at least none at my level of Japanese
ability. So is this a term that is used? If not, is there a better name for
the above-mentioned orthography?




Edited: Both Kotobank and Goo refer to this term, so it would seem legit. I
may ask a blind question of some HS teachers in Japan to get more
confirmation.

Additional information with example text in links: During the Meiji Period,
documents would be written in kanji with the grammar added using very small
katakana characters. Every year I was required to transcribe the Imperial
Rescript on Education at my job. It was written in this manner and some of the
kana had special uses, like fu in the place of u, as seen in the first
characters 'chin omou ni'.
