Open the CIPO recordAbstract From the Canadian patent
A system and method for enabling validation of an extensible markup language (XML) document having elements associated with two or more schemata where elements of each schema may be arbitrarily nested within elements from the other schema and each set of elements remains valid within it's own schema. Elements of the second schema are transparent to the elements of the first schema when the word-processor validates the elements of the first schema. The elements of the second schema are separately validated such that the elements of the first schema are transparent for the validation of the elements corresponding to the second schema.

Why it's free to use
- Filed June 25, 2003 and granted March 31, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 25, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 25, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
