Handling of blanks

In most cases, blanks are treated as white-spaces (i.e., insertion of blanks anywhere in the expression has no effect), except in the case of Field Selection Expressions (see Section 4). Blanks are allowed as part of the field names. Blanks around the delimiting characters (',' , ';' , '&' etc.) are ignored. For field names, blanks after the first valid name character and before the last valid name character are included as part of the name. Hence

• field=A , B , C is same as field=A,B,C
• field=A , BB BB , C is same as field=A,BB BB,C (first name is "A", second name is "BB BB" and the third name is "C")
• baseline=1 , 2 , 3 & 4 , 5 , 6 ; 10 $\sim$ 11 & 20 $\sim$ 30 is same as
  baseline=1,2,3&4,5,6;10$\sim$ 11&20$\sim$ 30
