19.275 "The filter is conjunctively added..." ? How is "conjunctively added" different from "added?"

Amend the descriptions of the values "query" and "table" in 19.258 form:command-type as follows: query: the command contains the name of query. The form retrieves the query and executes its SQL statement . table: the command contains a table name. The form executes an SQL statement that retrieves all of the data in the table. Replace the first paragraph of 19.275 form:filter as follows: The form:filter attribute specifies a filter for the SQL clause determined by the form:command-type and form:comand attributes. If that SQL statement contains already a filter (WHERE clause), the filter specified by the attribute value is is conjunctively added to the existing filter.
