/**
* \brief Class to manipulate Transfer Syntax
* \note
* TRANSFER SYNTAX (Standard and Private): A set of encoding rules that allow
* Application Entities to unambiguously negotiate the encoding techniques
* (e.g., Data Element structure, byte ordering, compression) they are able to
* support, thereby allowing these Application Entities to communicate.
*
* \todo: The implementation is completely retarded -> see gdcm::UIDs for a replacement
* We need: IsSupported
* We need preprocess of raw/xml file
* We need GetFullName()
*
* Need a notion of Private Syntax. As defined in PS 3.5. Section 9.2
*
* \see UIDs
