To define page-specific / unique-per-page values (still fully referable from outside the page ie. in templates, snippets and *.haxproj files), use custom P-tags.
For more versatile parameterized snippets with named variable value substitutions, declare an X-tag definition (or multiple) of type hax.snippet instead.
