4.92 - [eq] Built-In

Mnemonic aid: eq for EQual to zero content

See also:  [ne] 

If value is empty, the conditionalContent will be emitted. The style is only evaluated if value is empty. sep defaults to the comma.

Note: Please see  [even]  to learn how styles work with this operation.
Note:

conditionalContent is generated either way; the only difference is whether it appears in the output stream or not.

To avoid generating any content, put the sep character and nothing else.
