Did you check out the XML extensions in the marketplace?

I am using 'Auto Close Tag', 'Auto Rename Tag' and 'XML Tools (by Qub)'. And I checked 'XML Tools (by Josh Johnson)', 'XML Language Support' and 'XML Formatter',

This seems to be right issue for my feature request (if not, I'll open a new one).

I wish for XML a similar support as for HTML - in particular:

• Automatic closing of tags
• Automatic indentation while typing the tags
• Highlight of matching tag while the cursor is inside a tag (name).

The mentioned features are all supported by VS Code for HTML without any extensions and I didn't found anything in the marketplace for XML, besides of "Close HTML/XML tag" (that fulfills only the first wish).
