Release 2.0.0-alpha.8

Incremental release over 2.0.0-alpha.7.

Changes

• Selectors: an EFX expression can now identify the XML elements a reference points to, instead of the values held in them — &{reference} in EFX-1, and &{reference} or WITH context SELECT reference in EFX-2. The first use of it is privacy.undisclosedFieldSelector, which has to name the elements a notice viewer must withhold from publication.
• Preferred language selection: applied only while a view template is being translated, which is where the notice viewer's XSL variable it relies on actually exists.
• Context overrides (TEDEFO-5170): context::field now keeps the walk to its context, and any predicate written on that context. Until now the walk was shortened away and a written predicate was discarded, so ${field} and ${context::field} transpiled to the same thing and the override had no effect at all.
• Upgraded the eForms Core dependency, which now lets the caller decide how far a joined path may be shortened (TEDEFO-5169).

Impact on generated output

Expressions using a context override produce a longer path than before, one that yields nothing where the context is absent, and one that applies any predicate written on the context.

No SDK content is affected: context overrides are not used in any released SDK — every occurrence of :: in 1.13.3, 1.14.2, 1.15.1, 1.16.0-beta.2 and 2.0.0-alpha.3 is the preceding axis.

A predicate written on a node context attaches to a .. step, for example ../..[PathNode/IndicatorField = true()]. That is valid XPath 2.0 and is rejected by XPath 1.0.

XPathContextualizer.join takes a third argument and no longer offers the two-argument form. The toolkit is at a major version boundary, and a two-argument overload could only keep old callers working by applying the shortening this release exists to stop.
