SGML declaration: default |
If you parse an SGML document and do not supply an SGML declaration, the OmniMark SGML parser defaults to the
Reference Concrete Syntax. However, OmniMark does not default to the Reference Concrete Syntax values for SGML
quantity values such as NAMELEN
. Since the most common reason for using an SGML declaration is to raise
these quantities to larger values, OmniMark defaults to very large values for all the commonly used quantities.
This allows you to process most SGML documents without supplying an SGML declaration.
If you are attempting to validate an SGML document against the Reference Concrete Syntax, you may wish to include the SGML declaration for the Reference Concrete Syntax to validate SGML quantities correctly.
The values affected are:
ATTCNT
ATTSPLEN
BSEQLEN
DTAGLEN
DTEMPLEN
ENTLVL
GRPCNT
GRPGTCNT
GRPLVL
LITLEN
NAMELEN
NORMSEP
(OmniMark defaults to zero)
PILEN
TAGLEN
TAGLVL
The default SGML declaration used by OmniMark is:
