Serna document templates are *.sdt files that provide a convenient way to associate all necessary metadata with a certain document type.
A document template contains specified paths to XML metadata and other metadata that accompanies a document of a certain document type.
This helps to create a document of a particular document type with a single click. Also, most documents can be opened with a single click, because Serna automatically finds the document template which matches the document, and applies the appropriate schema, stylesheet, etc.
Serna document templates are closely connected with plugins. A document template specifies what plugins must be loaded for documents opened with this template. Also, Serna plugin description files ( *.spd) list document templates for which they must be loaded.
For instructions on how to create a new custom document template for your XML documents, see Introduction to Document Template Development.
If you do not have a document template, you may need to specify paths to the XSL stylesheet, XML schema, etc. manually . For instructions, see Creating a New Document without a Template.
