+      <p>When content is used as the accessible name of an element, the correct language should be specified on that element. This helps assistive technologies pronounce it accurately.</p>
+      <p>This link may be announced with an English accent, mispronouncing "Español".</p>

+        <p>Although marking only the <code>span</code> with a different language (as in the first example) is theoretically correct, current user agents and assistive 
+           technologies have limited and inconsistent support for handling language changes as part of their accessible name calculation and exposition. 
+           Since the <code>span</code> is the sole content of the link and contributes entirely to its accessible name, setting the language on the parent 
+           <code>a</code> element (as in the second example) is more reliable and ensures that screen readers pronounce the content correctly.</p>

+      <h3>Element content in multiple languages used as accessible name</h3>
+      <p>When content includes multiple languages, any child elements that use a different language must have their own <code>lang</code> attribute.</p>

+             Since the accessible name of this link contains multiple languages, it is required to mark each portion with the appropriate <code>lang</code>, either inherited or set explicitly,
