1. Linkable Text Field -->
   To facilitate allowing text in a wv-field-text and wv-field-select to be linked to a custom url.
   Use case :
   Consider two entities Order and Product, with a relationship between Order and Product. The Order LIst page displays a grid with a column displaying the product name. User needs to quickly and easily open the the product details page and see it's numerous fields ( The inventory for e.g.).
2. Multivalue Select - >
   To facilate displaying multiple fields from the bound entity in the EntityRecordListToSelectOptionConverter datasource.
   Use Case: In the order creation, the user needs to select a product based on its name or its sku and select the customer using their name or email or phone numer.
