My concern was that I would not be issued a SEAL Challenge Contract because of my age, if I WERE to have to use a second or third attempt I would be above the cutoff age. So that was my question. Sorry for the lack of detail.
Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C 's XML 1.0 Specification and by several other related specifications, all of which are free open standards.
For readers unacquainted with either term, HTML is the set of codes (that's the markup language) that a writer puts into a document to make it displayable on the World Wide Web. HTML 4 is the current version of it. XML is a structured set of rules for how one might define any kind of data to be shared on the Web.
