The value of a key-value pair that identifies the location of an attachment to a document. The format for
<b>Value</b> depends on the type of key you specify.
</p>
<ul>
<li>
<p>
For the key <i>SourceUrl</i>, the value is an S3 bucket location. For example:
</p>
<p>
<code>"Values": [ "s3://doc-example-bucket/my-folder" ]</code>
</p>
</li>
<li>
<p>
For the key <i>S3FileUrl</i>, the value is a file in an S3 bucket. For example:
</p>
<p>
<code>"Values": [ "s3://doc-example-bucket/my-folder/my-file.py" ]</code>
</p>
</li>
<li>
<p>
For the key <i>AttachmentReference</i>, the value is constructed from the name of another SSM document in your
account, a version number of that document, and a file attached to that document version that you want to reuse.
For example:
</p>
<p>
<code>"Values": [ "MyOtherDocument/3/my-other-file.py" ]</code>
</p>
<p>
However, if the SSM document is shared with you from another account, the full SSM document ARN must be specified
instead of the document name only. For example:
</p>
<p>
<code>"Values": [ "arn:aws:ssm:us-east-2:111122223333:document/OtherAccountDocument/3/their-file.py" ]</code>
</p>
