Microsoft Excel (using the default 1900 Date System) cannot display dates before the year 1900, although this is not due to a two-digit integer being used to represent the year: Excel uses a floating-point number to store dates and times. The number 1.0 represents the first second of January 1, 1900, in the 1900 Date System (or January 2, 1904 ...
The "/" operator is generalized in XPath 2.0 to allow any kind of expression to be used as an operand: in XPath 1.0, the right-hand side was always an axis step. For example, a function call can be used on the right-hand side. The typing rules for the operator require that the result of the first operand is a sequence of nodes.
Compared to XPath 2.0, XPath 3.0 adds the following new features: . Inline function expressions Anonymous functions can be created in an expression context. For example, the expression function ($ a as xs:double, $ b as xs:double) as xs:double {$ a * $ b} creates a function that returns the product of its two arguments.
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, [1] and can be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document.
During this time text/xsl became the de facto standard. In XSLT 1.0 it was not specified how the media-type values should be used. With the release of the XSLT 2.0, the W3C recommended in 2007 the registration of the MIME media type application/xslt+xml [ 21 ] and it was later registered with the Internet Assigned Numbers Authority .
The leap year problem (also known as the leap year bug or the leap day bug) is a problem for both digital (computer-related) and non-digital documentation and data storage situations which results from errors in the calculation of which years are leap years, or from manipulating dates without regard to the difference between leap years and common years.
The XQuery and XPath Data Model (XDM) is the data model shared by the XPath 2.0, XSLT 2.0, XQuery, and XForms programming languages. It is defined in a W3C recommendation . [ 1 ] Originally, it was based on the XPath 1.0 data model which in turn is based on the XML Information Set .
A "basic" XSLT 2.0 processor is unable to use data typing information. Saxon offers strict conformance to the XSLT 2.0, XPath 2.0 and 3.0, and XQuery 1.0 and 3.0 W3C Recommendations, and also implements XML Schema 1.0 and 1.1. As of 2021 the current version (10.6) conforms with the W3C Recommendations for XSLT 3.0, XPath 3.1, and XQuery 3.1.
