scope:

ISO/IEC 9541, as a whole, specifies the architecture of font resources, as well as the formats for font interchange among information processing systems. It also specifies the architecture and formats that can be used to construct font references in general electronic document interchange. This part of ISO/IEC 9541 specifies the architecture and interchange formats of glyph shape representations. Font resources represented using the architecture and interchange formats defined in ISO/IEC 9541-1 and ISO/IEC 9541-2 are used in various document processing environments in which RELAX NG (ISO/IEC 19757-2) parsing algorithm is recognized. The encoding of font resource information as defined in this part of ISO/IEC 9541 is specified in RELAX NG representation for consistent generation of font resources for use in these processing environments.
