# Working with TW Regulatory Submissions (RIM)

When working with Taiwan regulatory submissions, Submissions Publishing allows you to generate TW eCTD DTD 1.0, 2.0, and 2.1 compliant XMLs for submission to TFDA. Vault can validate these submissions in accordance with the TW TFDA 1.0, 2.0, and 2.1 Validation Criteria Version.

## About Node Extensions & Study Tagging Files

The Taiwan eCTD specification supports both node extensions and Study Tagging Files (STFs) in the same submission. If your submission contains both node extensions and STFs, they must exist in separate content plan sections.

## Copying a Content Plan for TW Submissions

When [copying a content plan](/en/lr/37472/#copy-from-content-plan) from another submission, Vault removes all country-specific data with the exception of the STF _Content Plan Item_ record to support other regions that accept STFs. In order for the publishing process to work correctly for copied submissions, you must set the _Continuous Publishing_ and _Continuous Validation_ fields to **Yes** on all _Content Plan Items_.

## Viewing & Managing Submission Administrative Information

Vault supports viewing Submission Administrative Information for TW 1.0, 2.0, and 2.1 DTDs. You can also manage Submission Administrative Information for TW 1.0, 2.0, and 2.1 DTDs. When you manage Submission Administrative Information for Taiwan submissions, the viewer displays envelope information to be populated. See [Managing Submission Administrative Information](/en/lr/52665/) for details.
