 ## Functionality
 When topics are requested, they are pulled from the cache, if they exist; otherwise, they are pulled from the underlying `ITopicRepository` implementation, and then cached. Similarly, when topics are e.g. saved, the updated versions are persisted to the underlying `ITopicRepository`, and then updated in the cache.

 ## Types
 User-defined table valued types are used to relay arrays of information to (and between) the stored procedures. These can be mimicked in C# using e.g. a `DataTable`. These include:
 - **[`AttributeValues`](Types/AttributeValues.sql)**: Defines a table with an `AttributeKey` `Varchar(128)` and `AttributeValue` `Varchar(255)` columns.
-- **[`TopicList`](Types/TopicList.sql)**: Defines a table with a single `TopicId` `Int` column for passing lists of topics.
