Define a grammar for the properties language with */com/simpleplugin/Simple.bnf* file.
```java
{% include /code_samples/simple_language_plugin/src/com/simpleplugin/Simple.bnf %}
{
parserClass="com.simpleplugin.parser.SimpleParser"
extends="com.intellij.extapi.psi.ASTWrapperPsiElement"
psiClassPrefix="Simple"
psiImplClassSuffix="Impl"
psiPackage="com.simpleplugin.psi"
psiImplPackage="com.simpleplugin.psi.impl"
elementTypeHolderClass="com.simpleplugin.psi.SimpleTypes"
elementTypeClass="com.simpleplugin.psi.SimpleElementType"
tokenTypeClass="com.simpleplugin.psi.SimpleTokenType"
}
simpleFile ::= item_*
private item_ ::= (property|COMMENT|CRLF)
property ::= (KEY? SEPARATOR VALUE?) | KEY
```
As you see a properties file can contain properties, comments and line breaks.
