By using non-spatial attribute information in the data, we can create a map
like this:

This is what the mapfile looks like: `Example1-3.map<http://biometry.gis.umn.edu/tutorial/example1-3.map>`_.

Our mapfile still only has two layers but the polygon layer has been broken down
into two classes. Let's have a look at the additional parameters:
**CLASSITEM**
-This keyword is used to specify what attribute to use in separating the class
-objects. In this example that attribute is "CLASS". If you open the database
-file associated with this layer's shapefile, you'll see that there's a column
-(attribute) called "CLASS".

-How do we know which attribute to use? Well, database records in
- shapefiles are stored in DBF files. You can open it in a
- spreadsheet program such as Openoffice.org's Calc, or in a desktop
- GIS software such as QGIS, Thuban, or ArcView. If your data came
- with a metadata (and it should!), you can skim through through that
- metadata file for attribute information. You can also use "ogrinfo"
- to display basic attribute info in your shapefiles--look back at
- example 1.1 (the last few lines after "Layer SRS WKT:" show the
- attribute names and types).

**EXPRESSION**
-For each class, we specify what attribute value to use. This is the
- simplest form of EXPRESSION. EXPRESSIONs can be even more complex
- than this, allowing one to evaluate regular or logical expressions.
- Please look at the mapfile reference page to see what you can do
- with EXPRESSION.
