Hi @NehaCMS ,
In AEM, there are several OOTB selectors that are used by Sling to determine how a resource is rendered. These selectors are typically used to modify the behavior or output of a resource. Here are some of the commonly used OOTB selectors in AEM:
1. `.html`: This selector is used to render the resource as HTML. It is the default selector used by Sling if no other selector is specified.
2. `.json`: This selector is used to render the resource as JSON. It returns the resource data in JSON format.
3. `.feed`: This selector is used to render the resource as a feed, such as an RSS or Atom feed.
4. `.print`: This selector is used to render a printer-friendly version of the resource.
5. `.tidy`: This selector is used to render the resource with additional formatting or cleanup applied.
6. `.infinity`: This selector is used to enable pagination for a resource, allowing the retrieval of a subset of the resource's content.
7. `.nopage`: This selector is used to exclude the resource from being included in a page.
8. `.txt`: This selector is used to render the resource as plain text.
These are some of the commonly used OOTB selectors in AEM. It's important to note that these selectors are part of the default behavior of Sling and are generally safe to use. However, it's always a good practice to review and validate the selectors used in your codebase to ensure they align with your specific requirements and do not conflict with any internal implementations.
