conversion to XSD, adding documentation
wrapper of language versions
A definition file may potentially contain more versions and language versions.
definitions in one language, for a certain version and language

Language of the definitions
hierarchical element for storing definitions related to a section
Sections do not have definitions
hierarchical element for storing definitions related to a class
Classses may have definitions.
hierarchical element for storing definitions related to a subclass.
A IPCDefinitionsSubclass usually has definitions, and can contain definitions for (some of) its maingroups, stored under the IPCDefinitionsMaingroup elements.
hierarchical element for storing definitions related to a maingroup.
While it is not mandatory to have definition for the main group, embedded subgroups may have their own definition.
 flat list of subgroups
wrapper of the definition of the group
A subgroup must have exactly one definition.

DEFINITION-TITLE was made optional (some definitions have no title)
 empty symbol denotes IPC-wide, global definitions (terms)
definition title
Title is optional and irrelevant.

Contains:

  • and an optional table(s) of local references in complex subclasses
the definition cases, optional
explanations
This element appears twice in DEFINITION-STATEMENT when no DEFINITION-CASE precedes the explanation.
optional table(s) of local references
explanations
optional table(s) of local references
relationship between large subject matter areas
 headings for subsequent explanations explanation, at least one
tables containing limiting references
tables containing information references
one or more reference tables, a reference table may have a preceding heading
references that do not belong to a subheading
 headings for reference tables
references that belong to a subheading
 special rules of classification in form of explanations glossary: terms often used in IPC within this class, subclass, maingroup or group
synonyms and keywords often used in patent documents
Definition of a subject matter area of the actual class, subclass, maingroup or group
A main paragraph (explanation)
Index of groups with a heading.
 table of references
heading, for tables or explanations
Headings in definitions are not embedding its content.
