Re: Why Doesn't IE5 use the DTD to Validate?

[James Clark <jjc@xxxxxxxxxx>]

Reading the DTD and validating aren't the same thing.  Unless a document
has standalone="yes", the browser should always read a provided DTD so
that it can correctly

- default attributes
- normalize attribute values
- expand entity references

None of these things involve validation.
