The structure and fields of the Cache Glyph (Revision 1) Secondary Drawing Order are specified in section 188.8.131.52.1.2.5. The order fields MUST be processed in accordance with this description.
If the client does not support glyph caching (specified in the Glyph Cache Capability Set described in [MS-RDPBCGR] section 184.108.40.206.8) or the GlyphIndex (section 220.127.116.11.1.2.5), FastIndex (section 18.104.22.168.22.214.171.124), and FastGlyph (section 126.96.36.199.188.8.131.52) Primary Drawing Orders, this order SHOULD be ignored. Furthermore, if a client encounters any inconsistencies or errors when decoding and processing the Cache Glyph (Revision 1) Secondary Drawing Order, the connection SHOULD be dropped.
