Comment (by evands):

 Your patch would work around an `XML_ERR_INVALID_CHAR` error by parsing to
 the end and resetting the error info... but what if it were an uncoverable
 or systemic error, like ` XML_ERR_NO_MEMORY` or perhaps `
 XML_ERR_INTERNAL_ERROR`?  I'm afraid we could end up with an infinite
 loop.
