Advanced format in attribute values

As you may remember, even if a macro is in the advanced format, not all input fields in the Macro Editor expect a string to be placed in single quotes ('') (see Representation of strings and special characters, treatment of operator characters). Specifically, the advanced format affects input fields only on the following tabs of the Macro Editor:
Similarly, in the macro language, when you provide a string value for an attribute that corresponds to one of these input fields that is affected by the advanced format, you must enter the string in the advanced format. For example, in the <message> element the strings for both attributes must be written enclosed in single quotes, if the macro is in the advanced format:
<message title="'Instructions'"  value="'Check the java console'" />
However, if an attribute does not correspond to one of the input fields affected by the advanced format, then you should not write the value enclosed in single quotes, even if the macro is in the advanced formt. For example, the name attribute of the <screen> element should never be enclosed in single quotes:
<screen name="Screen1" entryscreen="true" exitscreen="true" transient="false" >
   ...
</screen>

In the descriptions in this chapter of macro language elements, this book indicates such attributes (attributes that are unaffected by the advanced format) by not specifying a data type. For example, the description of the name attribute of the <screen> element is "Required" rather than as "Required string".
