Module Svg_types

module Svg_types: sig .. end
SVG types with variants, goes with Svg_sigs.T.

This module defines basic data types for data, attributes and element occuring in SVG documents. It is based on the specification available at http://www.w3.org/TR/SVG/.

This module is experimental, it may lack of some attributes, and the interface is very low level and do not take deeply into account the needs of SVG elements.

Categories of elements and attributes



This part defines the categories of elements and attributes

Generic data types


type iri = string
An IRI reference is an Internationalized Resource Identifier with an optional fragment identifier, as defined in Internationalized Resource Identifiers RFC3987. An IRI reference serves as a reference to a resource or (with a fragment identifier) to a secondary resource. See References and the ‘defs’ element..
