+htmx's attributes and these attribute functions map one-to-one. There are two exceptions:
+- `_hxBoost` implies `true`; use `_hxNoBoost` to set it to `false`.
+- `_hxSwapWithTransition` renders the standard `hx-swap` attribute and appends `transition:true` to the specified swap value.
+
+The htmx `hx-on` attribute supports multiple events if they are separated with a newline (`\n`) character. The value provided to this attribute will be attribute-escaped, but in testing, it was interpreted correctly.

+The support modules contain named properties for known values (as illustrated with `HxTrigger.Load` above). A few of the modules are more than collections of names, though:
 - `HxRequest` has a `Configure` function, which takes a list of strings; the other functions in the module allow for configuring the request.
