Tag represents a Jelly custom tag. A Tag is only ever used by a single thread so that Tag developers do not need to concern themselves with mutli-threading issues when writing a Tag. A Tag is created per custom tag in a script, per invocation. So there is no need to worry about pooling errors like those caused in JSP 1.x.(
