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".

user wants a long article about "scrubber design calculation excel best". This likely refers to best practices for designing scrubbers (gas scrubbers) using Excel. I need to provide a comprehensive article covering key calculations, methodologies, Excel tips, and resources. To gather sufficient information, I should perform a broad search covering various aspects of scrubber design calculations in Excel. I will search for general guides, specific calculation methods for different scrubber types (like packed bed, venturi, wet scrubbers), available Excel spreadsheets and templates, and relevant best practices. search results provide a good starting point. I have identified several relevant resources: a general engineering calculations zip file, a LinkedIn post about scrubber sizing, an EPA document on packed-bed scrubber design, a venturi scrubber design guide, a wet scrubber design calculator, a free scrubber system sizing spreadsheet, a packed column scrubber design spreadsheet, and a book on air pollution control equipment calculations. To gather detailed information for the article, I will open these resources. opened resources provide a wealth of information. I have details on various engineering calculations, a spray tower guide, a LinkedIn post on scrubber sizing, an EPA document on packed-bed scrubber parameters, design equations for venturi scrubbers, a guide to venturi scrubber design, a thread with attachments, a LinkedIn post with a free spreadsheet, and a list of Excel spreadsheets. I also have information on packed column scrubber design and other relevant links. To ensure a comprehensive article, I should also search for best practices in Excel for engineering calculations, and possibly specific tutorials or templates. I will also search for "scrubber design calculation Excel free download" and "scrubber design Excel sheet" to find more resources. search results provide a good amount of information. I have information on Excel best practices, several free spreadsheet resources, and a specific example of a packed scrubber design sheet. I also have the previously opened resources. Now I need to structure the article. I will cover an introduction to scrubbers and the importance of Excel, key design parameters and formulas for packed, venturi, and spray towers, Excel best practices for engineering calculations, a step-by-step guide to building a calculation sheet, resources and templates, validation and verification, and a conclusion. The article should be detailed, practical, and useful for engineers. I will cite the sources appropriately. Mastering Scrubber Design Calculations in Excel: A Comprehensive Guide for Engineers
to optimize L/G ratios.
The most common source of scrubber design errors is unit mismatch (e.g., mixing Standard Cubic Feet per Minute (SCFM) with Actual Cubic Feet per Minute (ACFM)). This likely refers to best practices for designing

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.
