# cxxFunctionNameLookup

Provides a unique identifier of the function.

## Description

This element provides a way of uniquely identifying a function in a body of DITA XML that describes a body of C++ source code.

Implementations are free to write what they want in this element's PCDATA but a "good" implementation would place some premium on the following:

- The text would be unique within a set of DITA XML files.
- The text would be human readable.
- The text would generally follow the lookup techniques use in the C++ standard (ISO/IEC 14882:2003(E)).
- Any encoding used would be reversible.
