Text Value Templates - xspec/xspec GitHub Wiki
Just like XSLT 3.0's Text Value Templates, { } in embedded XML can be evaluated dynamically.
Enabling/disabling TVT is controlled by @expand-text (or @x:expand-text within embedded XML). For example:
<x:context expand-text="yes">
<test>{1 to 9}</test>
</x:context><x:context>
<test x:expand-text="yes">{1 to 9}</test>
</x:context>In both cases, <test> is expanded:
<test>1 2 3 4 5 6 7 8 9</test>(@x:expand-text is removed.)
