+Modifications:
-Part I: Preamble (define detector objects, variables)
+(19-Jun)
+  - Removed end blocks
+  - Added function arguments (e.g arg1, arg2,..)
+  - Renamed SR to CUT
+  - Inheritance explicitly defined by key 'contains'
+  - Changed cut language to select/reject
+  - Added new info block "units"
 The idea is to write a plain text file that can be read easily into
-xml if needed (and hence universally readable).  The name of the block become sthe xml tag.  Anything that follows is turned into attributes. e.g. "name ATLAS" inside the block becomes <experiment name="ATLAS">.  Anything inside the block starting with "#" is added as a comment, i.e. the first block below automatically converts to
+xml if needed (and hence universally readable).  The name of the block become sthe xml tag.  Anything that follows is turned into attributes. e.g. "name ATLAS" inside the block becomes <experiment name="ATLAS">.  Anything inside the block starting with "#" is added as a comment, i.e. the block

-There are five types of pre-defined blocks -- detectorobj (defines reconstructed objects), function (defines functions that act on these), cut (blocks of cuts), SR (contains all cuts for a particular signal region) and results (for giving numbers).  Besides this, the user can define whatever they want -- e.g. here, "analysis" gives extra info, and "hist" gives a way to provide tables.
+There are five types of pre-defined blocks:
+  - **detectorobj** (defines reconstructed objects)
+  - **function** (defines functions that act on these)
+  - **cut** (blocks of cuts)
+  - **binning** (following Daniel's idea, for complex descriptions of orthogonal signal regions)
+  - **info** (for meta information chosen by the implementer, e.g. information about publication, conf-notes, theory papers used for interpretation, benchmarks, etc.)
-For any block, a link to code or external documentation can be provided.  We can also include a MCsamples block to document the programs used to generate signal and background samples.
+For presenting results, we need two more blocks, e.g.
+  - **results** (for expected, observed, S95, etc.)
+  - **table** (for providing digitised histograms etc.)
-When a block inherits the properties of other blocks (e.g. medium electron inherits from loose), the names of those can be added after the name of the current block.
+For any block, a link to code or external documentation can be provided.  We can also include a MCsamples block to document the programs used to generate signal and background samples.
