include pattern FAQ
This page document frequently asked questions about the include-pattern. For general questions about microformats see the microformats faq.
Q: Does include-pattern support for data outside of the current page?
A: No. The include-pattern is specifically scoped to the current page by design, both from a "vast majority of use cases" perspective, and a ease of implementation perspective.
Including data from external resources raises several issues:
- Unreliable (dependency and if/when the data is available)
- Security (possibly malicious data)
- Invisible (original context of the data is not available)
Q: What is the normative behavior for an include with a "data" value that does not exist?
Q: Is there an assumption that you should only include one property at a time? What's the expected behavior if, say, my include has an org property, and the including vcard already has an org property?
A: This would depend on two factors, if the format can contain multiple instance of the property included, then both are valid. If the format can only take one instance of a property, than the first should be used and subsequent instances ignored.
