# Working with CA Regulatory Submissions (RIM)

When working with CA regulatory submissions, Submissions Publishing allows you to generate CA eCTD v2.2 XSD compliant XMLs for submission to Health Canada. Vault can validate these submissions in accordance with CA eCTD Validation Criteria Profile v5.2.

## About Node Extensions & Study Tagging Files

The CA eCTD specification supports both Study Tagging Files (STFs) and node extensions in the same submission. If your submission contains both node extensions and STFs, they must exist in separate content plan sections. If your submission contains an STF XML, Vault creates STFs instead of node extensions.

    <div class="alert-text">
      <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 CA Submissions

When [copying a content plan](/en/lr/37472/#copy-from-content-plan) from a US submission, Vault removes all US-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 CA 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 CA v0.9 and v1.0 XSDs. You can also view and manage Submission Administrative Information for CA v 2.2 XSDs. See [Managing Submission Administrative Information](/en/lr/52665/) for details.
