Any and ever form submission, no matter how simple or complex, can be represented as a single file encoded in Particle Syntax with semantics provided by the Parsers programming language.

Thus, any one filling out any form, no matter how complicated the form (tax returns, electronic medical records, mortgage applications, LSATs, et cetera), could in theory type the form in a single plain text document encoded in Particle Syntax, OR use an HTML multi input form which generates that text document under the hood, or a hybrid of both, since they are isomorphic to each other.
