Editing Interpress (section)

===Example===

{| style="border-spacing: 2px; border: 0px; font-family:monospace; white-space:nowrap;"
|-
| style="width: 320px;" | Header "Interpress/Xerox/3.0 "||  style="width: 210px;" | --standard header--
|-
| {instructions}|| --device instructions--
|-
| BEGIN || --start of master--
|-
| &nbsp; &nbsp;  {preamble} || --preamble--
|-
| &nbsp; &nbsp;  {page 1} || --first page--
|-
| &nbsp; &nbsp;  {page 2} || --second page--
|-
| END || --end of master--
|}

A more complex structure would include Nested Blocks and CONTENTINSTRUCTIONS, a token used to distinguish content-instructions bodies from page bodies. In general, the content instructions are given precedence over the document instructions. Nested Blocks {BEGIN..END} allow for constructing large documents out of smaller ones.
