__NOTOC__ This is a placeholder for the feature. Closely allied with [[AVT]] Erik's notes: * eXforms proposal: http://exforms.org/variable.html * Orbeon implementation: http://wiki.orbeon.com/forms/doc/developer-guide/xforms-variables * could also prefer the shorter <var> tag name, especially if we go with a @value attribute instead of a @select attribute == Proposal == * You can define variables everywhere outside xf:model, as a child of model or as as child of an xforms action (even if it is in the model) ** Scoping: *** A given variable is visible to any XPath expression on a following sibling element or on a following sibling element's descendant element. *** Model variables are also visible from XPath expression outside of models whenever that model is in scope. * Binds automatically create variables with their id as name of the variable -> Sounds really handy, but not yet sure where the variables should be available '''See [[Variables_in_XPath]]''' ---- [[Category:XForms20]]
