* **Explanation:** This focuses on the customer-facing implications of stock quantities, how it affects the knowledge of product availability, and focuses on practicality.

**Key Considerations When Choosing a Description:**
* **Target Audience:** Who is reading this description? Is it intended to be read by the admin/author (in which case more detail is fine) or by the customer (in which case readability is key)?
* **Purpose of the Tag:** What function does the “stock quantity” tag serve in your WordPress site? Does the description need to include any hints on its relation to other data fields or attributes?
* **Word Count:** WordPress description boxes can be limited. Choose a description that will stay within the bounds.
