#362 Clarify use of bvar in lambda element of FunctionDefinition

[Sarah Keating]

Section 4.3.2
We state that a <lambda> element can contain zero or more <bvar> elements BUT we dont mention the fact that a <bvar> element must contain one and only one <ci> element. No other elements are permitted within a <bvar> element.

I would suggest the text added to paragraph 1:

A <bvar> element must contain one and only one <ci> element. No other elements are permitted within a <bvar> element.

and an additional validation rule

20308: Inside the <lambda> MathML element within a FunctionDefinition any <bvar> elements must contain one instance of a <ci> element. No other elements are permitted within a <bvar> element.

Sorry dont know where the added <bvar> etc text comes from and if I try and edit the above they are not visible ??? !!</bvar>

Looks like you have to escape at least the '<' as & lt; Sigh.

I approve this change, and think it would be a good idea. It's clearly been a rule since forever; we just forgot to write it down, it seems.

[Matthias König]

I approve this change.

[Fengkai Zhang]

I agree with this change.

With 3 editors agreeing on an obvious issue, I have made this change to SVN, and it will be part of the forthcoming spec. I also added it to http://sbml.org/Documents/Specifications/SBML_Level_3/Version_2/Core/Confirmed_issues_in_the_Level_3_Version_2_Core_Specification#Release_1_.28Final.29

[Lucian Smith]

Released.
