This command validates the current document or
a document specified in the argument against a DTD,
RelaxNG or XSD schema.
If --yesno or :q is specified, only prints
yes and returns 1 if the document validates or
no and returns 0 if it does
not. Without --yesno, it throws an
exception with a complete validation error message if
the document doesn't validate.
--dtd or :D forces DTD validation
(default).
--relaxng or :R forces RelaxNG
validation. Only XML RelaxNG grammars are supported.
--schema or :S forces W3C XML Schema
validation (XSD). Support for schema validation may still
be incomplete (see libxml2 home page
for more details).
A DTD subset can be specified by its PUBLIC identifier (with
--public), by its SYSTEM identifier
(with --file), or as a string (with
--string). If none of these options is
used, validation is performed against the internal or
external DTD subset of the document being validated.
RelaxNG grammars and XML Schemas can either be
specified either as a filename or url (with
--file),
as a string containing (with --string),
or as a document currently open in XSH2 (with
--doc).
