The construct parameters can be written with the following options (all are optional):
* "**~**" or "**@**": sampler (for compatibility with *Dynamic Prompts*), but only "**~**" (random) is supported.
* "**~**" (random) or "**@**" (cyclical): sampler (for compatibility with *Dynamic Prompts*). The cyclical sampler cycles through all combinations in order across consecutive `process_prompt` calls, resuming where the previous call left off (as long as the input prompt and negative prompt do not change).
* "**r**": means it allows repetition of the choices.
* "**o**": means it is "optional", and no error will be raised if there are no choices to select from.
* "**n**" or "**n-m**" or "**n-**" or "**-m**": number or range of choices to select. Allows zero as the start of a range. Default is 1.

* `(red<ppp:stn>square<ppp:/stn>:1.5)` will end up as `(square:1.5)` in the negative prompt
* `(red[<ppp:stn>square<ppp:/stn>]:1.5)` will end up as `(square:1.35)` in the negative prompt (weight=1.5*0.9) if the merge attention option is enabled or `([square]:1.5)` otherwise.
* However `(red<ppp:stn>[square]<ppp:/stn>:1.5)` will end up as `([square]:1.5)` in the negative prompt. The content of the negative tag is copied as is, and is not merged with the surrounding modifier because the insertions happen after the attention merging.
* `(red<ppp:stn>[square]<ppp:/stn>:1.5)` will also end up as `(square:1.35)` in the negative prompt if the merge attention option is enabled, because the content of the negative tag is a single attention construct whose weight is merged with the surrounding modifier.
