This schema document describes the XML namespace, in a form suitable for import by other schema documents.
See http://www.w3.org/XML/1998/namespace.html and http://www.w3.org/TR/REC-xml for information about this namespace.
Note that local names in this namespace are intended to be defined only by the World Wide Web Consortium or its subgroups. The names currently defined in this namespace are listed below. They should not be used with conflicting semantics by any Working Group, specification, or document instance.
See further below in this document for more information about how to refer to this schema document from your own XSD schema documents and about the namespace-versioning policy governing this schema document.
denotes an attribute whose value is a language code for the natural language of the content of any element; its value is inherited. This name is reserved by virtue of its definition in the XML specification.
Attempting to install the relevant ISO 2- and 3-letter codes as the enumerated possible values is probably never going to be a realistic possibility.
See BCP 47 at http://www.rfc-editor.org/rfc/bcp/bcp47.txt and the IANA language subtag registry at http://www.iana.org/assignments/language-subtag-registry for further information.
The union allows for the 'un-declaration' of xml:lang with the empty string.
denotes an attribute whose value is a keyword indicating what whitespace processing discipline is intended for the content of the element; its value is inherited. This name is reserved by virtue of its definition in the XML specification.
denotes an attribute whose value provides a URI to be used as the base for interpreting any relative URIs in the scope of the element on which it appears; its value is inherited. This name is reserved by virtue of its definition in the XML Base specification.
See http://www.w3.org/TR/xmlbase/ for information about this attribute.
denotes an attribute whose value should be interpreted as if declared to be of type ID. This name is reserved by virtue of its definition in the xml:id specification.
See http://www.w3.org/TR/xml-id/ for information about this attribute.
denotes Jon Bosak, the chair of the original XML Working Group. This name is reserved by the following decision of the W3C XML Plenary and XML Coordination groups:
In appreciation for his vision, leadership and dedication the W3C XML Plenary on this 10th day of February, 2000, reserves for Jon Bosak in perpetuity the XML name "xml:Father".
First, let’s clear up a common misconception. The "AM/FM Unit" label can be misleading. The UI-7 does not add AM or FM transmission modes to a radio. Instead, the name refers to the fact that this unit controls the —specifically the Volume (AM) and Squelch (FM) —along with a programmable function key.
"Listen," Maya said. He did. Somewhere beyond the harbor, across distances measured not only in miles but in memory, the UI-7 exhaled a static that was almost like a greeting. The boy's eyes widened. He could not yet name the stations; he did not yet know the weather patterns. But he understood the gift: that certain machines are conduits for more than signal—that they hold the patience of people, the kindness of strangers, the steady insistence that someone, somewhere, was telling a story. icom ui-7 am fm unit
The Icom UI-7 AM/FM unit is a highly integrated and versatile module that offers a range of features and capabilities for amateur radio communication. Its compact size, low power consumption, and high performance make it an attractive solution for manufacturers and hobbyists looking to build or upgrade their amateur radio equipment. Whether you're building a handheld radio, mobile radio, or repeater system, the Icom UI-7 is definitely worth considering. First, let’s clear up a common misconception
On a salt-streaked harbor where gulls argued like old friends, a small repair shop leaned into the wind between a lighthouse and a row of weathered boats. Its glass door had a sticker that read RADIO REPAIRS — in letters long since sun-bleached — and inside, amid soldering irons and coils of coaxial cable, sat an object that had once been the heart of a thousand voyages: an Icom UI-7 AM/FM unit. Instead, the name refers to the fact that
If you’ve ever pressed the "AM/FM" button on an Icom IC-725 and nothing happened, it’s because the UI-7 wasn't installed. This unit was an optional upgrade that officially unlocked the radio's ability to: (usually at 10–40 watts).
The Icom UI-7 is an optional internal plug-in module designed primarily for Icom’s line of VHF/UHF base stations and receivers from the late 1980s and early 1990s.
In keeping with the XML Schema WG's standard versioning policy, this schema document will persist at http://www.w3.org/2009/01/xml.xsd.
At the date of issue it can also be found at http://www.w3.org/2001/xml.xsd.
The schema document at that URI may however change in the future, in order to remain compatible with the latest version of XML Schema itself, or with the XML namespace itself. In other words, if the XML Schema or XML namespaces change, the version of this document at http://www.w3.org/2001/xml.xsd will change accordingly; the version at http://www.w3.org/2009/01/xml.xsd will not change.
