# Working with AU Regulatory Submissions (RIM)

When working with Australian regulatory submissions, Submissions Publishing allows you to generate AU eCTD XSD 3.2 compliant XMLs for submission to the Australian Therapeutic Goods Administration (TGA). Vault can validate these submissions in accordance with the AU TGA v3.2 Validation Criteria Version.

## About Node Extensions & Study Tagging Files

In certain situations, the Australian 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.

      <p><strong>Note</strong>: The title of a node extension or STF is controlled by the <em>Content Plan Title</em> field. The title field has a limit of 1500 characters. However, for publishing of STF and node extensions a hard limit of 255 characters is enforced.</p>

## Copying a Content Plan for AU Submissions

When <a href="/en/gr/37472/#copy-from-content-plan">copying a content plan</a> 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 AU 0.9, 3.0, 3.1 and 3.2 XSDs. You can also manage Submission Administrative Information for AU 3.1 XSDs.

When you manage Submission Administrative Information for Australian submissions, the viewer automatically groups the _Sequence Type_ and _Sequence Description_ attributes in the _Sequence Type_ row to support worksharing. Vault populates each attribute based on the submission's _Submission Type_ and _Submission Subtype_, respectively.

You can add an override to support additional _Sequence Types_ and _Sequence Descriptions_ in work-grouping submissions. When you <a href="/en/gr/52665/#using-overrides">add an override</a> for the _Sequence Type_, Vault displays a pre-filtered list of _Controlled Vocabulary_ records with _Submission Type_ and _Submission Subtype_ set for _Controlled Vocabulary Type_, as well as _AU_ selected for _HA Code Source_.
