1. The upstream docs contain multiple instances of hyphenated user-replaced values such as <user-replaced-value> instead of the underscored syntax `<user_replaced_value>` {}of RH supplementary style guide.

2. I've also come across instances of user-replaced values such as `${value}` or ` value}` instead of the underscored syntax `<user_replaced_value>` {}of RH supplementary style guide.

NB: Instances starting with render as `${` in the published docs.
