Description

The start pattern defines the “start” of a grammar. When this grammar is used to validate a complete document, the start pattern specifies which elements can be used as the document (root) element. When this grammar is embedded in another grammar, the start pattern specifies which pattern should be applied at the location where the grammar is embedded. Like named pattern definitions, start patterns may be combined by choice or interleave and redefined when they are included in include patterns.

Example

<start> <element name="library"> <oneOrMore> <ref name="book-element"/> </oneOrMore> </element> </start> <start combine="choice"> <ref name="book-element"/> ...
