Many HDML statements allow you to specify options. Individual options have the following syntax:
option=value
option is a string of alphanumeric characters for which case is ignored. value can contain alphanumeric characters or nonalphanumeric characters. If the value contains white space you must enclose it in single (') or double (") quotation marks. If it contains reserved HDML characters (such as <, >, or $), you must escape these characters, using URL escaping conventions. If the value contains only alphanumeric characters, quotation marks are optional, although it is strongly recommended that you use them. HDML syntax does not allow white space between the key, the equal sign, and the option value.
Many HDML statements allow you to specify an option list, or a concatenation of individual options separated by white space. The syntax for an option list is:
option1=value1 option2=value2 option3=value3 . . .
