/**
* DomSanitizer helps preventing Cross Site Scripting Security bugs (XSS) by sanitizing
* values to be safe to use in the different DOM contexts.
*
* For example, when binding a URL in an `<a [href]="someValue">` hyperlink, `someValue` will be
* sanitized so that an attacker cannot inject e.g. a `javascript:` URL that would execute code on
* the website.
*
* In specific situations, it might be necessary to disable sanitization, for example if the
* application genuinely needs to produce a `javascript:` style link with a dynamic value in it.
* Users can bypass security by constructing a value with one of the `bypassSecurityTrust...`
* methods, and then binding to that value from the template.
*
* These situations should be very rare, and extraordinary care must be taken to avoid creating a
* Cross Site Scripting (XSS) security bug!
*
* When using `bypassSecurityTrust...`, make sure to call the method as early as possible and as
* close as possible to the source of the value, to make it easy to verify no security bug is
* created by its use.
*
* It is not required (and not recommended) to bypass security if the value is safe, e.g. a URL that
* does not start with a suspicious protocol, or an HTML snippet that does not contain dangerous
* code. The sanitizer leaves safe values intact.
*
* @security Calling any of the `bypassSecurityTrust...` APIs disables Angular's built-in
* sanitization for the value passed in. Carefully check and audit all values and code paths going
* into this call. Make sure any user data is appropriately escaped for this security context.
* For more detail, see the [Security Guide](https://g.co/ng/security).
