User:Khannatanmai/Wordbound blanks

This page will follow the development of word bound blanks in the apertium stream format.

Rationale

Wordbound blanks will store information about a lexical unit that can help us with several applications where we want to send information through the pipeline but this information can't be sent as tags because it would break the FST matching in the modules.

Formalism

Wordbound blanks will be denoted by double square brackets and will always appear right before a Lexical Unit.

[[wordboundblank]]^LU<tags>$

Examples
