I have 4 custom tabs on the product detail page.
How to add the tag to the tab heading.
catalog_product_view.xml
<block class="Magento\Catalog\Block\Product\View" name="magneticBallastTable.tab" template="VENDOR_Dvpage::tabs/content.phtml" group="detailed_info" >
<arguments>
<argument translate="true" name="title" xsi:type="string">Product Versions Comparison</argument>
<argument name="sort_order" xsi:type="string">70</argument>
</arguments>
</block>
