ModifierHtmlSchema

HTML open tag emitted on copy. May contain the literal placeholder {value} for the modifier's tag parameter.

HTML close tag emitted on copy. Typically the matching </element>.

Case-insensitive HTML element names this schema matches on paste. Never; never empty.

Optional callback that derives the UniText modifier parameter from the raw attribute slice of a matched HTML element on paste. Receives the substring between the element name and the closing > — e.g. for <span style="color:red"> the callback receives style="color:red". Returns the parameter value to splice into the UniText source tag (e.g. "red"), or when the element does not actually express this modifier (in which case the adapter keeps the inner content but does not wrap it). callback means the modifier is parameterless.

Optional converter applied to the modifier's tag parameter before it substitutes {value} on copy. Returning skips this schema's wrapper for the span (the content still copies) — invalid CSS is never emitted. converter means the parameter is already a valid CSS value.

Whether OpenTagTemplate carries the {value} placeholder — such a schema cannot emit without a parameter.
