I don't know how you are defining meaning, which makes it difficult for me 
to evaluate what you are saying here.

Is it wrong for HTML to define something called an HREF attribute, and to 
give that attribute semantics that allow link checking to be applied to any 
HTML document? That gives it meaning within one vocabulary, and expected 
behavior among some classes of applications that use this data.

Is it wrong for XML to have ID/IDREF attributes, with associated semantics, 
and allow attributes to be declared to be of this type?

Is it wrong for SQL or Java to have datatypes?

Justify your answer ;->
