README:
This directory contains a program to read a DTD, and produce a compressed
representation of it. It's intended that this program be run at build
time, and the resultant .bdtd binary DTD file be read at program startup.
.dtdb FILE FORMAT
file ::= version_no:int num_names:short name[]:string num_entities entity[]
num_elements element[]
entity ::= name_id:short type:byte data:string
element ::= name_id:short type:byte
flags:byte (&0x01 = omit start, &0x02 = omit end)
content_model
num_exclusions:byte name_id[]
num_inclusions:byte name_id[]
num_attributes:byte attribute[]
attribute ::= name_id:short type:byte modifier:byte
value:name_id (or -1 for null)
num_values:short name_id[]
content_model ::= content_c | content_e | content_null
content_null ::= flag:byte=0
content_c ::= flag:byte=1 type:int content:content_model next:content_model
content_e ::= flag:byte=2 type:int element_name_id next:content_model
string ::= modified UTF-8 encoding of a string
See the java.io.InputStream class description for the specification of modified
UTF-8.
