Selecting values that are not associated with one side of a many to many relationship

Question

I have a junction table between categories and values that indicate which categories are associated with which each value. I would like to find the values that are not associated with each category.

Category:

ID CategoryName
-- ------------
 1 category1
 2 category2
 3 category3

CategoryValue:

CategoryID ValueID
---------- -------
         1       1
         1       2
         2       1
         3       2

Value:

ID ValueName
-- ---------
 1 value1
 2 value2
 3 value3

The output I would like for the query is the following:

CategoryID ValueID ValueName
---------- ------- ---------
         1       3 value3
         2       2 value2
         2       3 value3
         3       1 value1
         3       3 value3

I'm pretty stuck on how to approach this as a query. The "junction" table seems to prevent the usual LEFT JOIN WHERE null approach. So any advice would be much appreciated.
