Usealloftoextendreferenceschemas

The “usealloftoextendreferenceschemas” attribute in HTML is used to specify whether an element in an HTML document can use all of the types of values allowed in the reference schema.

When the attribute is set to “usealloftoextendreferenceschemas”, the element is allowed to use any value that conforms to the reference schema. This means that the element can accept values that are not explicitly listed in the reference schema.

Here is an example:

    
      <script src="https://example.com/script.js" usealloftoextendreferenceschemas></script>
    
  

In the above example, the <script> element has the “usealloftoextendreferenceschemas” attribute set. This means that the element can use any value allowed in the reference schema for the <script> element.

It’s important to note that the “usealloftoextendreferenceschemas” attribute is not a standard attribute in HTML and is not supported by all browsers. It should be used with caution and only when necessary.
