You can specify macro code to be inserted at the very beginning of each HTML output file, and entity references to be inserted before the <head> element:
[Inserts] ; location = macro to insert, can call another macro ; BeginFile is placed at the very start of the file ; Entities is placed before the HEAD element
To specify an entity reference, create a macro with the entity reference code as the body of the macro, and indicate that the macro is to be placed before the <head> element. For example:
[Inserts] Entities=<$MyEntities>
[MyEntities] <!ENTITY % HTMLlat1 PUBLIC "-//W3C//ENTITIES Latin 1//EN//HTML"> %HTMLlat1; <!ENTITY % HTMLsymbol PUBLIC "-//W3C//ENTITIES Symbols//EN//HTML"> %HTMLsymbol;
Entity references are placed before the <head> element in each HTML output file, including split and extracted files.
