ALF_ — StructuredMember should be renamed to StructuredElement

In order to play with ALF I have thrown together a parser for my own use.
Along the way I have found a small error in the spec regarding the Abstract Syntax for ALF. Many clauses in the spec (Beta 1) refer to 'StructuredElement' and those same clauses say that StructuredElement is defined in clause 10.4.4. However, in clause 10.4.4 the element appears to be named 'StructuredMember' instead.

It looks to me like StructuredMember should be renamed to StructuredElement since the term 'Element' appears to be the convention used throughout the rest of the spec.

The intent was actually to change StructuredElement to StructuredMember (which is a better name for it), but the rest of the document outside Subclause 10.4.4 does not seem to have been properly updated for this (note that the parser grammar in the Annex uses StructuredMember).
