ISO/IEC TR 20000-10:2015 describes the core concepts of ISO/IEC 20000, identifying how the different parts support ISO/IEC 20000 1:2011 as well as the relationships between ISO/IEC 20000 and other International Standards and Technical Reports. This part of ISO/IEC 20000 also explains the terminology used in ISO/IEC 20000, so that organisations and individuals can interpret the concepts correctly.

ISO/IEC TR 11581-1:2011 introduces the ISO/IEC 11581 series and provides developers and other icon standards users with an overview of currently available and future anticipated icon standards.
ISO/IEC TR 11581-1:2011:
- describes the structure of parts that will be used to encompass all present and future icon standards;
- introduces currently existing icon standards, whether they are parts of ISO/IEC 11581 or they have their own separate numbers

ISO/IEC TS 11581-41:2014 provides guidance for developers and designers creating and/or using icons and provides a basis for the standardization of icons. It also provides a framework for creating future International Standards dealing with icons as parts of the ISO/IEC 11581 series and for identifying icon-related information to be used in any accompanying icon registries. It is intended to be used with ISO/IEC 11581-40 to create a registry of icons.

ISO/IEC TR 19075-1:2011 describes the regular expression support in SQL adopted from the regular expression syntax of XQuery 1.0 and XPath 2.0 Functions and Operators (Second Edition), which is derived from Perl. It discusses five operators using this regular expression syntax:
- LIKE_REGEX predicate, to determine the existence of a match to a regular expression.
- OCCURRENCES_REGEX numeric function, to determine the number of matches to a regular expression.
- POSITION_REGEX function, to determine the position of a match.
- SUBSTRING_REGEX function, to extract a substring matching a regular expression.
- TRANSLATE_REGEX function, to perform replacements using a regular expression.

This Technical Report gives mechanisms for formally specifying the syntax of XML-based languages. For example, the syntax of XHTML 1.0 can be specified in RELAX.
Compared with DTDs, RELAX provides the following advantages:
- Specification in RELAX uses XML instance (i.e., document) syntax,
- RELAX provides rich datatypes, and
- RELAX is namespace-aware.
The RELAX specification consists of two parts, RELAX Core and RELAX Namespace. This part of the Technical Report gives RELAX Core, which may be used to describe markup languages containing a single XML namespace. Part 2 of this Technical Report gives RELAX Namespace, which may be used to describe markup languages containing more than a single XML namespace, consisting of more than one RELAX Core document.
Given a sequence of elements, a software module called the RELAX Core processor compares it against a specification in RELAX Core and reports the result. The RELAX Core processor can be directly invoked by the user, and can also be invoked by another software module called the RELAX Namespace processor.
RELAX may be used in conjunction with DTDs. In particular, notations and entities declared by DTDs can be constrained by RELAX.
This part of the Technical Report also gives a subset of RELAX Core, which is restricted to DTD features plus datatypes. This subset is very easy to implement, and with the exception of datatype information, conversion between this subset and XML DTDs results in no information loss.
