Re: [Xsltforms-support] binding to text nodes - what am I doing wrong?

[Tim T. <tim...@gm...>]

This is a very valuable piece of functionality. Thank you, Michael, for
raising the issue, and Alain for the implementation. I notice in the
current draft of the XForms 2.0 spec, under section 8.1.2, there is a note
that reads:

"The simpleContent binding restriction is intended to allow controls to
bind to attribute and element nodes. This specification does not prevent
binding controls directly to text nodes, however doing so can yield
undesirable behavior, such as a form control becoming non-relevant if a
user enters empty data. This specification also does not prevent
implementers supporting binding controls directly to comment or processing
instruction nodes, however the resulting behavior is
implementation-dependent and may also yield undesirable behavior."

Notwithstanding, if there are use cases that require the ability to bind
directly to text nodes, I hope it would merit inclusion in an eventual
XForms 2.0 Test Suite.
