Attributes

Example

<?xml version="1.0" encoding="utf-8"?>
<grammar xml:lang="en-US" root="BlueGreen" tag-format="semantics/1.0" version="1.0" 
xmlns="http://www.w3.org/2001/06/grammar">

<!-- This rule recognizes the color names "blue", "indigo", "azure", "green", --> 
<!-- "teal", and "emerald", and returns the text of the recognized color and --> 
<!-- a semantic value. -->
