conformant to W3C XML Conformance Test Suite
multiple parsing APIs (DOM, SAX2, XmlReader)
HTML parser for error-tolerant HTML 4.01 parsing
XPath 1.0 support
validation against DTD, RelaxNG, and XSD
Canonical XML serialization
XInclude document inclusion processing
XML Catalogs for URI resolution
CLI tool for parsing, validating, and querying XML

Article: 21 min

An article discussing the typographic error in the 'H' lettering on the Unity Temple entrance designed by Frank Lloyd Wright, exploring its history and potential causes.

The article discusses the inverted 'H' on the bronze lettering above Unity Temple's doors.
Jonathan Hoefler, a typographer, spotted the error during his visit to Chicago.
The temple underwent gunite treatment in 1973, which may have introduced or preserved the error.
The letters were stolen and replaced in 2012, with new lettering installed again in 2014.
A $25 million restoration was completed from 2014 to 2017, but an upside-down 'H' was introduced during this period.

Quality:
The article provides a detailed analysis of the typographic error and its history, without expressing personal opinions.

Discussion (9):

The comment thread discusses various opinions on architectural lettering and typography, comparing historical practices to modern ones. It also mentions a controversial article that might be disturbing or sensitive.

The typography and lettering are bespoke, not a mistake.
Hand lettering is not equivalent to a typeface.
