 A template is constructed from a charstream. Everything that is not in "<?" to "?>" will be outputted directly. Text in these markers will be interpreted is template scripting syntax. The following strings are valid:
 
-- <?=$variblename?> will output "variablename".
+General remarks:
+- $variablename: a variablename matches the regex [a-zA-Z0-9_-]
+Syntax:
+- <?=$variablename?> will output "variablename".
    if "variablename" is an Outputable output this thing recursively.
    else turn it into a String (Object.toString()) and output it.
+
+- <?=$!variablename?> will output the variable "variablename" but not HTML-escaped
    
 - <?=_This is free Text.?> will translate "This is free Text." into the users language, (escaped) and output it.
-   
-- <?=s,$var1,$var2,$var3,...,$varn,This %s is, %s free.?>
-  Translate the last string. Output $var1,...,$varn replaced into the %s positions in the translated string.
-  
-- <? if($variable) { ?>
-  Output/execute the text until "<? } ?>" only if $variable not null or Boolean.FALSE.
-  
-- <? foreach($variable) { ?>
+	Text may not contain "?>".
+	If the text contains "$" or "!'" it is interpreted as "advanced replacement".
+	   - ${variablename} is interpreted as "output this variable at this point"
+	   - $!{variablename} is interpreted as "output this variable unescaped at this point"
+	   - !(/link) is interpreted as "output an opening <a>-tag to '/link' at this point" (which must be closed, e.g. using !'</a>', see below)
+	   - !'literal content' output "literal content" here and do not translate or escape. (literal content may not contain any of: {}'$   )
+	Then the whole text than also may not contain "{" and "}".
+
+- <? if($variable) { ?> ... <? } ?>
+  Output/execute the text until "<? } ?>" only if $variable is Boolean.TRUE (<=> !Boolean.FALSE) or not null. 
+- <? if(...) { ?> ... <? } else { ?> ... <? } ?>
+
+- <? foreach($variable) { ?> ... <? } ?>
   If $variable is an "IterableDataset"
   Output/execute the text until "<? } ?>" repeated as $variable suggests. 
   Special variables that $variable defines can be used in the inner text.
  
   
-  
\ No newline at end of file
+Adding a "\" before a newline will cause both the backslash and the newline get removed. This allows non-visible line-breaks in templates.
+Note: Mail templates consist of a template for subject and a template for the body. Prolonging the subject-line with this feature is not possible.
