Who are the yatis of the Jain Śvetāmbara romance-poems (8th-12th century CE)?

In pre-modern Jain literature and in the writings of early 20th century CE scholars, the terms yati and caityavāsin, as applied to ascetics, have taken on a very pejorative connotation and have been used to refer to dissenting monks known for their lax practices. Strikingly, the term yati already appears as an equal to śramaṇa and muni in about ten long narrative works, mainly in prose and verse, written by monks between the 8th and 12th centuries CE. The aim of this paper is to examine in this under-explored corpus and in related works whether the use of the term yati applies to the so-called caityavāsins and if so, which type of monk it characterises in the complex and still shadowy monastic world of the turn of the first millennium.
