+overview: |
+  Parent tags are used to expand an external template into the current template,
+  with optional parameters delimited by block tags.
+
+  These tags' content MUST be a non-whitespace character sequence NOT containing
+  the current closing delimiter; each Parent tag MUST be followed by an End
+  Section tag with the same content within the matching parent tag.
+
+  Block tags are used inside of parent tags to assign data onto the context stack 
+  prior to rendering the parent template. Outside of parent tags, block tags are
+  used to indicate where value set in the parent tag should be placed. If no value
+  is set then the content in between the block tags, if any, is rendered.
