Sorts all attribute
from the SAX event attributes part
and from the DTM defintion into the appropriate diagnosis set
), according to the type check results.
"check()" should be called for a particular SAX event with a fresh instance.
By explicitly calling
all undeclared, type-violating and fixed-violating attributes are
reported to the message channel with the given location
Missing attributes are not, but must be treated explicitly by the caller.
The location information in theses error messages is (opaquely) the one supplied on
creation, because in SAX contexts it comes with only coarse granular anyhow.
This is separated from the check(), because in the meantime
in particular contexts attribute errors can be healed (cf xslt
"attribute value templates", "use-attribute-set" attribute, etc.)
The "ignore" set is introduced for the "use-attribute-set" attribute
(and some more) from xsl.
FIXME nötig !? besser einfach nach UNDEF, dann wieder raus !?!
TDOM has its own checks, compiled into the constructor code,
but these are not so complete (currently eg. undeclared atts are not
ATTENTION: Attributes of type ID IDREF IDREFS ENTITY ENTITIES and NOTATION
must follow the "name" production, see XML section 3.3.1.
Attributes of type NMTOKEN, NMTOKENS and ENUMERATION
need only follow the nmtoken production.
A name is an nmtoken which STARTS with an alphabetic character or underscore "_"
or colon ":". An NMTOKEN may additionally start with "." or "-" or a digit.
