Regular fields in a document are best described as?

Regular fields in a document are best defined as any fields found in a document. This broad definition encompasses various elements within the document that capture specific pieces of information, regardless of their nature or purpose. Regular fields can include names, dates, addresses, amounts, or any identifiable data that can be extracted or processed.

While certain fields like expense types or headers can certainly be considered regular fields, they only represent a subset of the entire scope of fields that might be present in a document. Therefore, a definition that encompasses all possible fields is more accurate and comprehensive. This recognition of regular fields allows for a more versatile approach in automating document processing and analyzing the data within those documents.
